Defendant Roy Brown appeals the district court’s award of attorney’s fees under the Civil Rights Attorney’s Fees Awards Act of 1976, 42 U.S.C. § 1988 , arguing, inter alia, that the amount of attorney’s fees awarded should be reduced further. Plaintiffs cross-appeal arguing that the district court improperly reduced the amount of attorney’s fees owed to them.

I

Lillian Corder and Roberta Lombardo brought suit on the basis of the civil rights statute, 42 U.S.C. § 1983 . Plaintiffs alleged that defendants illegally detained them and conducted an illegal search of their residence in a misguided attempt to find an escaped prisoner. Specifically, plaintiffs alleged in their complaint that on January 18, 1985 they resided together at 4630 Live Oaks in Cudahy, California and at approximately 3:00 a.m. defendants stormed plaintiffs’ residence, ordered them from their home, and detained them for approximately five hours without pressing legal charges. Plaintiffs further claimed that defendants “absent any warrant ... shot out the windows of the home, entered the home, shot chemical gas into the home, [and] shot out the ceiling of the home.... ”

Plaintiffs named as defendants the following individuals and entities: Orange County Sheriff Brad Gates, twenty-five Orange County deputy sheriffs, Los Angeles County Sheriff Sherman Block, twenty-five Los Angeles deputy sheriffs, Bell/Cudahy police chief Frank Fording, ten Bell/Cu-dahy police officers, the County of Los Angeles, the County of Orange, the City of Bell, and the City of Cudahy. Roy Brown, the highest ranking Los Angeles County Sheriff’s officer present during the operation, authorized the entry of plaintiffs’ home.

On September 30, 1985, defendants made a $45,000 settlement offer, which plaintiffs rejected. 1 This offer included the $39,000 worth of plaintiffs’ attorney’s fees that had then accrued, leaving the plaintiffs with $6,000.

After trial, the jury, by special verdict, awarded damages in favor of Lillian Corder as follows: $1.00 in compensatory damages and $5,000 in punitive damages against Bell/Cudahy Police Sergeant Stanton Lo-der; $1.00 in compensatory damages and $10,000 in punitive damages against Orange County Sheriff’s officer Keith Brown; and $1.00 in compensatory damages and $1000 in punitive damages against appellant, Commander Roy Brown of the Los Angeles County Sheriff’s Department. The jury awarded damages in favor of Roberta Lombardo as follows: $1.00 in com *377 pensatory damages and $2,500 in punitive damages against Stanton Loder; $1.00 in compensatory damages and $5,000 in compensatory damages against Keith Brown; and $1.00 in compensatory damages and $500 in punitive damages against appellant Roy Brown. The total compensatory and punitive damages amounted to $24,006. The district court subsequently awarded plaintiffs $90,333 in attorney’s fees.

Plaintiffs cross-appeal arguing that the district court erred when it adjusted the fee award downward to reflect limited success. Defendant Roy Brown appeals. Brown makes three arguments: First, Brown argues that the attorney’s fees awarded by the district court must be reduced further to account for plaintiffs’ limited success; second, Brown argues that the district court must apportion liability for attorney’s fees among defendants in accord with their relative culpability, claiming that each defendant’s relative culpability is reflected in the proportion of the overall jury verdict that is directed against him; third, Brown argues that the district court must decrease his liability for attorney’s fees to account for fees already paid by other defendants through settlement. 2

District court awards of attorney’s fees under section 1988 are reviewed for abuse of discretion. Hensley v. Eckerhart, 461 U.S. 424, 437 , 103 S.Ct. 1933, 1941 , 76 L.Ed.2d 40 (1983); Cabrales v. County of Los Angeles, 864 F.2d 1454, 1464 (9th Cir. 1988), vacated on other grounds, 490 U.S. 1087 , 109 S.Ct. 2425 , 104 L.Ed.2d 982 (1989), reinstated, 886 F.2d 235 (9th Cir. 1989), cert. denied, — U.S. —, 110 S.Ct. 1838 , 108 L.Ed.2d 966 (1990). As such, the district court’s fee award will be overturned if it is based on an inaccurate view of the law or a clearly erroneous finding of fact. See Cabrales v. County of Los Angeles, 935 F.2d 1050 (9th Cir.1991); Hunt v. National Broadcasting Co., 872 F.2d 289, 292 (9th Cir.1989) (reviewing denial of preliminary injunction).

Ill

Section 1988 authorizes the district courts to award a reasonable attorney’s fee to prevailing parties in civil rights litigation. “The purpose of § 1988 is to ensure effective access to the judicial process for persons with civil rights grievances.” Hensley, 461 U.S. at 429 , 103 S.Ct. at 1937 (quotation omitted). “Congress has elected to encourage meritorious civil rights claims because of the benefits of such litigation for the named plaintiff and for society at large_” Blanchard v. Bergeron, 489 U.S. 87, 96 , 109 S.Ct. 939, 945-46 , 103 L.Ed.2d 67 (1989).

Blanchard highlights the principles that govern appellate review of district court fee awards. The Blanchard Court addressed the question whether a fee agreement between a plaintiff and her lawyer acted as a cap on the amount of attorney’s fees that a district court could find “reasonable.” The Court held that the discretion of the district courts to award “reasonable” fees is not circumscribed by fee agreements, though the district courts have liberty to consider such agreements when determining a “reasonable” fee. 489 U.S. at 94 , 109 S.Ct. at 944-45. Defendant argued that failing to “cap” fees would result in a “windfall” to plaintiff’s attorneys. The Court responded:

Id. at 96, 109 S.Ct. at 945-46.

Blanchard evidences three principles. First, discretionary judgments of the district courts, which watch civil rights cases unfold before them, must be respected. Second, the discretion of the district courts must not be unduly limited by mechanistic rules. Third, fee awards must ensure that civil rights lawyers receive reasonable compensation for their services. 3 This third principle limits the district court's discretion, for this third principle underlies the requirement that the district courts carefully calculate hours and rates and fully articulate their reasoning. See Hensley, 461 U.S. at 437 , 103 S.Ct. at 1941 .

A

We first consider whether the method used by the district court to calculate attorney’s fees was both incorrect and harmful, so that its fee award must be invalidated. The district court first determined the reasonable rate of compensation, and the reasonable number of hours worked, then multiplied hours by rate to arrive at the presumptively reasonable fee that is known as the “lodestar” figure. Hensley, 461 U.S. at 433-37 , 103 S.Ct. at 1939-41 . The district court then adjusted this “lodestar” figure to account for the plaintiffs’ limited success.

We have held that the procedure followed by the district court in calculating fees is disfavored. Cunningham v. County of Los Angeles, 879 F.2d 481, 487-88 (9th Cir.1988), cert. denied, 493 U.S. 1035 , 110 S.Ct. 757 , 107 L.Ed.2d 773 (1990); Cabrales, 864 F.2d at 1464 . Since consideration of limited success is presumably “subsumed within the initial calculation of hours reasonably expended at a reasonable hourly rate,” district courts should not ordinarily make a separate adjustment for limited success. Cabrales, 864 F.2d at 1464 (quoting Hensley, 461 U.S. at 434 n. 9, 103 S.Ct. at 1940 n. 9.).

However, the fact that the district court followed a disfavored procedure for calculating fees does not necessarily nullify the district court’s fee award. In Cabrales the district court followed the same procedure for calculating fees as was followed in the instant case, yet we affirmed the fee award because the record showed that “the district court made only one reduction for lack of success.” Cabrales, 864 F.2d at 1465 . We said:

Cabrales, 864 F.2d at 1465 .

In the instant case, as in Cabrales, the district court partitioned its “lodestar” analysis from consideration of plaintiffs' degree of success, and accounted for plaintiffs limited success only once. Thus, any error was harmless.

B

We turn to the substance of the district court’s fee award. Since the parties accept the district court’s calculation of the “lodestar” amount, the question is whether the district court abused its discretion when it reduced the lodestar figure by 20% to account for plaintiffs’ limited success. 4

It is clear that a 20% reduction for limited success is in some cases sustainable. In *379 Cabrales, 864 F.2d at 1454 , plaintiff sued the county, the commander of the county jail, and a number of other jail employees. Plaintiff was the mother of former jail inmate Sergio Alvarez Cabrales. Cabrales, despite his obvious psychiatric problems, was not given needed medical attention, and was housed in facilities used for the general inmate population. While in solitary confinement, Cabrales hanged himself. Plaintiff originally brought suit against twenty or more individual sheriffs deputies who worked at the jail, but succeeded only on her claim that the county, through its policymaker Black, maintained a policy of deliberate indifference to the safety and medical needs of inmates. 864 F.2d at 1458 .

We upheld the district court’s 25% reduction for limited success. 864 F.2d at 1466 . We said:

Id. at 1465 (citations omitted). See also Hensley, 461 U.S. at 435-36 , 103 S.Ct. at 1940-41 .

In the instant case, all of the claims arose from a “common core of facts,” the search of plaintiffs’ house. Further, all of the claims are “based on related legal theories,” the Fourth Amendment. However, since the plaintiffs succeeded against only a few defendants, a reduction for limited success was permissible. Cabrales, 864 F.2d at 1466 . 5 “The purpose of a fee award is to encourage litigation and voluntary compliance with civil rights laws.” Woods v. Graphic Communications, 925 F.2d 1195, 1207 (9th Cir.1991) (citations omitted). In cases such as the present one, where a plaintiff brings an action against a large number of defendants, but manages to prevail only with regard to a few, perhaps an award granting 100% of the ac *380 crued attorney’s fees encourages too much litigation. While it is true that the plaintiffs succeeded in proving a civil rights violation, they did so at the cost of forcing many individuals to bear the expense of defending against apparently meritless allegations. Such an award implicitly approves the plaintiffs strategic decision to pull in as many potential defendants as possible in an attempt to hold someone liable. Plaintiffs initially accused more than fifty defendants of violating their civil rights, yet obtained a verdict against three. 6 Thus, to say that the plaintiffs succeeded in the instant case does not mean that their success was not limited. 7 Obviously, then, the district court would have sound reasons for reducing a fee award in this type of a situation.

On the other hand, our cases also make clear that the district court could have awarded plaintiffs the full lodestar amount. In Rivera v. City of Riverside, 763 F.2d 1580 (9th Cir.1985), aff'd on other grounds, 477 U.S. 561 , 106 S.Ct. 2686 , 91 L.Ed.2d 466 (1986), plaintiffs sued thirty-two defendants, including thirty individual police officers. Plaintiffs prevailed against only six officers, winning a verdict totaling $33,350. 477 U.S. at 564 , 106 S.Ct. at 2689 . In Rivera , as in Cabrales, all of the plaintiffs’ claims stemmed from a single incident and involved a common core of facts. Nevertheless, we held that the district court did not abuse its discretion when it declined to reduce the attorney’s fee award for limited success, despite the plaintiffs’ failure to prevail against the majority of the original defendants. Thus, Cabrales and Rivera together indicate that district courts have considerable discretion in determining attorney’s fees, a rule that is in conformity with the teachings of Blanchard and Hensley . 8

Despite the discretion evidenced by Cabrales and Rivera , we have held that the district courts must clearly articulate sound reasons in support of their fee awards. Cunningham, 879 F.2d at 483-84 . For although the district courts must be given much discretion to shape awards of attorney’s fees, these awards must be subject to appellate review, and they must be reversed if based on clearly erroneous considerations. See Hensley, 461 U.S. at 437 , 103 S.Ct. at 1941 ; Cunningham, 879 F.2d at 483-84 .

In the instant case the district court’s 20% reduction of the “lodestar” amount was based on clearly erroneous reasoning and cannot stand. The district court first reasoned that Rule 68 of the Federal Rules of Civil Procedure did not govern because the jury’s verdict, when combined with the attorney’s fees that had accrued before the defendants’ pretrial settlement offer was made, exceeded the defendants’ offer. 9 Corder v. Gates, 688 *381 F.Supp. 1418, 1420-21 (1988). Yet the district court cited plaintiffs’ rejection of the settlement offer when reducing the attorney’s fee award for limited success, stating that the result of plaintiffs’ decision to proceed to trial “was to win a much smaller figure than they could have obtained much earlier by simply accepting defendants’ offer.” Corder, 688 F.Supp. at 1423 . As the district court recognized in its discussion of Rule 68, plaintiffs gained over $18,000 by litigating their case to its conclusion. We reverse, remand, and provide the district court with another opportunity to consider whether an adjustment to the lodestar amount is appropriate. See United States v. State of Washington, 935 F.2d 1059 (9th Cir.1991).

IV

We next consider whether the district court abused its discretion when it declined to allocate the attorney’s fee award among the individual defendants. 10 Brown argues that the district court must apportion liability for attorney’s fees among defendants in accord with their relative culpability, claiming that each defendant’s relative culpability is reflected in the proportion of the overall jury verdict that is directed against him.

Three recent Ninth Circuit cases have dealt with the issue of apportionment. 11 In Southeast Legal Defense Group v. Adams, 657 F.2d 1118, 1125-26 (9th Cir.1981), plaintiffs sued both state and federal defendants to enjoin construction of a freeway built by the state but funded by the federal government. Plaintiffs prevailed on one of their twelve claims. Thus, attorney’s fees were available to plaintiffs under section 1988. See Jensen v. City of San Jose, 806 F.2d 899, 900 (9th Cir.1986) (en banc). However, the federal defendants were exempted from liability for their share of attorney’s fees by 28 U.S.C. § 2412 . Adams, 657 F.2d at 1125 . The district court apportioned 75% of the attorney’s fees to the state defendants, who were the primary focus of the plaintiffs’ action. We faced the question whether the district court abused its discretion when it executed this lopsided apportionment. We held that, since “probably at least 75% of plaintiffs’ counsel’s preparation dealt with the state defendants, as opposed to the federal defendants,” the district court had not abused its discretion. Adams, 657 F.2d at 1125-26 .

We again considered apportionment of attorney’s fee liability among defendants in Sable Communications of California v. Pacific Telephone & Telegraph Co., 890 F.2d 184 , 194 (9th Cir.1989). Sable, a *382 “phone sex” company, brought suit against Pacific Bell under section 1983. Sable sought to enjoin Pacific Bell from interfering with Sable’s operations. General Telephone intervened in the suit as an additional defendant. Sable won both its injunction and $150,000 in attorney’s fees, fees for which General Telephone and Pacific Bell were to be jointly and severally liable. On appeal, we held that the district court had abused its discretion when it failed to apportion the attorney’s fee award between Pacific Bell and General Telephone. We said: “If, as appears likely, the conduct of Pacific Bell was the focus of the litigation and required a larger portion of the time of plaintiff’s counsel, it is appropriate to allocate the burden of the fee award accordingly.” Sable, 890 F.2d at 194. 12

Our most recent decision is Woods v. Graphic Communications, Inc., 925 F.2d 1195, 1206 (9th Cir.1991). Woods brought a section 1981 action against his employer, Princeton Packaging, Inc. (“Princeton”), and his union, alleging racial harassment that interfered with his ability to enforce his labor contract. Woods prevailed in the district court and was awarded attorney’s fees under section 1988. For purposes of apportioning fees between the union and Princeton, the district court divided the lawsuit into three phases. Phase I consisted of work performed before the union was a party to the lawsuit. Phase II included work performed while both Princeton and the union were parties, and Phase III included work performed after Princeton was dismissed. The union did not challenge the court’s award of fees for half of Phase II and all of Phase III, but the union did argue that it should not be liable for a portion of the fees incurred during Phase I. We acknowledged that the party that is the focus of the litigation should ordinarily bear the bulk of the litigation’s costs. Nevertheless, we held that the district court in Woods did not abuse its discretion in allotting a portion of Phase I fees to the union, since a portion of Woods’ efforts had been directed at the union even during Phase I, and “[t]he district court considered the union’s arguments on a motion for reconsideration and reduced the union’s share for Phase II.” Woods, 925 F.2d at 1207 .

All three of our apportionment cases have focused on the time expended by the plaintiff in pursuing each defendant when deciding whether apportionment was proper. Woods, 925 F.2d at 1207 ; Sable, 890 F.2d at 194; Adams, 657 F.2d at 1125-26 . Accord Koster v. Perales, 903 F.2d 131 , 138-40 (2d Cir.1990) (holding apportionment not mandated because, inter alia, the state failed to show that less overall time was expended against it than was expended against its codefendants); Little Rock School Dist. v. Pulaski County Special School Dist., 787 F.2d 372 , 374 (8th Cir. 1986) (in a case involving intervenors, the circuit court apportions fees based on time expended), cert. denied, 476 U.S. 1186 , 106 S.Ct. 2926 , 91 L.Ed.2d 554 (1986); Knights of Ku Klux Klan v. East Baton Rouge Parish School Board, 735 F.2d 895, 901 (5th Cir.1984) (upholding the district court’s allocation of 90% of attorney’s fees to the federal government, since the federal government played the major role in the dispute underlying the lawsuit).

The focus on time expended in Adams, Sable, and Woods is consistent with the “lodestar” calculation, which forms the basis for the overall attorney’s fee award, and which focuses on the time reasonably expended by plaintiffs. Hensley, 461 U.S. at 433-34 , 103 S.Ct. at 1939-40 . Indeed, the consistency of Adams, Sable, and Woods with the “lodestar” is an important virtue. It would make little sense to determine the overall liability of all defendants based on one consideration, then determine the individual liability of defendants based on an entirely different consideration. Thus, since the total amount of attorney’s fee liability faced by any group of defendants is based on the *383 number of hours that the plaintiff reasonably expended against them, the defendants’ rights inter se should share this feature. And under Adams, Sable, and Woods , the defendants’ rights inter se do share this feature.

Brown argues, purportedly on the basis of Adams and Sable, that the district court must apportion attorney’s fees in accord with each defendant’s relative liability under the jury’s verdict. As we have just seen, Adams and Sable provide little support for this argument. Moreover, Brown has simply misapprehended the purpose of attorney’s fees under section 1988. Attorney’s fees are not awarded to punish defendants. Attorney’s fees are awarded to encourage meritorious civil rights actions by ensuring reasonable compensation for victorious plaintiffs’ attorneys. Blanchard, 489 U.S. at 96 , 109 S.Ct. at 945-46 ; Hensley, 461 U.S. at 429 , 103 S.Ct. at 1937 . Thus, we have prescribed apportionment of attorney’s fees when the time expended by the plaintiff in pursuing each defendant was grossly unequal. Sable, 890 F.2d at 194. We have never mandated apportionment based on each defendant’s relative liability under a jury’s verdict. Brown’s rule “would negate the discretionary power granted the district court[s] under the Act,” and we reject it. Adams, 657 F.2d at 1125 . 13

Applying the rule of Adams, Sable, and Woods to the instant case, we see that a single incident led to the liability of all of the defendants, and that Brown was integrally involved in this incident. Indeed, Brown authorized the entry of plaintiffs’ home that gave rise to their lawsuit. Thus, the bare circumstances of the instant case do not support an inference that the plaintiffs expended less time pursuing Brown than they expended pursuing his codefend-ants. Cf. William C. Haas v. City & County of San Francisco, 605 F.2d 1105 , 1117 (9th Cir.1979) (no abuse of discretion for district court to allocate attorney’s fees based on percentage of time each defendant was involved in the breach of contract that formed the basis for the suit). Moreover, Brown has offered no evidence that plaintiffs expended less time pursuing him than they expended pursuing his codefend-ants. In these circumstances, the district court did not abuse its discretion when it declined to apportion liability for attorney’s fees among defendants.

V

Finally, Brown argues that the district court abused its discretion when it failed to offset the attorney’s fee award to account for fees that have been paid through settlement. We face a record that is entirely devoid of information about these alleged post-trial settlements; we have little information about either the number of settlements that have taken place, or the amount of these settlements. An appellate court may properly decline to reach issues not addressed by the court below in order to obtain both a fully developed record and the benefit of the district court’s treatment of the issue. See Golden Nugget, Inc. v. American Stock Exchange, Inc., 828 F.2d 586 (9th Cir.1987). Since we are poorly positioned to resolve the offset issue, we do not now reach it. On remand, the district court should inquire into the matter.

AFFIRMED in part, REVERSED in part, and REMANDED.

. Roberta Lombardo accepted this offer, but Lillian Corder rejected it. The district court held that, since the offer was made to both of the plaintiffs, it had to be accepted by both them, and Roberta Lombardo's acceptance of the offer was therefore ineffective. Corder v. Gates, 688 F.Supp. 1418, 1420 (C.D.CaI.1988). This ruling has not been appealed and it therefore binds the parties.

. Roy Brown claims on appeal that after trial, but before the hearing at which attorney’s fees were set, unspecified defendants who were found liable at trial executed settlement agreements of uncertain terms with the plaintiffs. Brown further claims that, after attorney’s fees were awarded, additional settlement agreements were executed between certain unspecified defendants and the plaintiffs.

. Nevertheless, it is clear that an award of a "reasonable” attorney’s fee may be made to a prevailing plaintiff notwithstanding the fact that the plaintiffs attorney has agreed to accept a smaller fee, or even no fee at all. Blanchard, 489 U.S. at 95 , 109 S.Ct. at 945 . Similarly, the "reasonable” fee, as calculated by the district court, may fall short of the actual fee that the plaintiffs lawyer charges. Id.

. Plaintiffs argue that the lodestar amount should not have been reduced at all for limited success. Defendants argue that the lodestar amount must be reduced further.

. Our recent decision in Cabrales v. County of Los Angeles, 935 F.2d 1050 (9th Cir.1991) (“Cab-rales VII") in no way undercuts Cabrales.

. By the time of the pretrial conference, all but 37 of the originally named parties were dismissed.

. Moreover, reducing the award in this situation serves as a deterrence for future plaintiffs and will force them to move cautiously before bringing suit against individuals only tangentially related to instant case.

. The dissent is in error when it states that this panel must follow Rivera and ignore Cabrales. Generally, to the extent that a panel is confronted with an irreconcilable intra-circuit conflict, the proper procedure is to call for en banc reconsideration. Antonio v. Wards Cove Packing Co., 810 F.2d 1477 , 1478-79 (9th Cir.1987) (en banc), cert. denied, 485 U.S. 989 , 108 S.Ct. 1293 , 99 L.Ed.2d 503 (1988). As stated above, however, we do not believe Rivera and Cabrales are in conflict.

. Rule 68 provides in relevant part:

Fed.R.Civ.P. 68 (emphasis added).

The plaintiffs' attorneys had accrued $39,000 in fees at the time of the $45,000 Rule 68 offer. Because successful plaintiffs are entitled to attorney's fees under section 1988, we must consider the amount of attorney's fees accrued at the time of the offer when deciding whether the plaintiffs improved their positions by going to trial. The jury verdict of $24,000 plus the pre-offer accrued fees of $39,000 exceeded the $45,-000 Rule 68 offer. Thus, because the plaintiffs *381 improved their position by rejecting defendants’ offer and going to trial, Rule 68 did not control.

. Contrary to plaintiffs’ assertions, the apportionment issue was raised below. See Fed. R.Civ.P. 46.

. Brown invokes authority from other circuits to support his argument that apportionment of attorney’s fees based on relative fault is mandatory. The strongest case for Brown is Dean v. Gladney, 621 F.2d 1331 (5th Cir. 1980). Yet even Dean does not lend Brown compelling support. The case involved a police riot in which numerous separate acts were committed by officers acting independently of each other. Id. at 1332-33 . For example, an Officer Maddox locked four women in an unventilated police car for one and one-half hours. An Officer Saldivar indiscriminately arrested numerous citizens and threatened a woman who was taking pictures of the riot.

The Dean court made two rulings that are relevant to the question of apportionment of attorney’s fees. First, the court held that the district court properly declined to assess attorney’s fees against certain defendants who had not been held liable to plaintiff. Liability on plaintiff's claim was held to be a prerequisite to liability for attorney’s fees. The rule is the same in this circuit. Jensen v. City of San Jose, 806 F.2d 899 (9th Cir. 1986) (en banc). But this rule offers Brown no solace, since he has been held liable.

The Dean court also held that officers whose liability is based on distinct incidents should have attorney’s fees assessed against them on an individual basis. Again, this holding offers Brown little solace. For the Dean court based its view that fees should be apportioned on the fact that the incidents from which the defendants’ liabilities arose were separate and discreet. 621 F.2d at 1338-39 . In contrast, in the instant case all of the defendants' liabilities arose from a single incident. Further, the actions of the defendants in the instant case were not independent. Rather, defendants actions were centrally controlled and were part of a common course of conduct.

. In Sable we were also concerned with the federal policy of facilitating interventions in civil rights cases in order to avoid piecemeal litigation. Sable, 890 F.2d at 194. This federal policy would be substantially prejudiced by application of a rule that saddled intervenors like General Telephone with attorney’s fees that accrued before the intervenor joined the lawsuit.

. Brown also claims that language in Sable suggests that district courts must subjectively evaluate each defendant’s culpability, then apportion attorney’s fees in accord with this evaluation. Even if Sable requires that the district courts engage in free-form, subjective evaluations of each defendant's culpability, a point that is not obvious, the district court's refusal to apportion cannot be challenged on that basis in the instant case. Brown authorized the invasion of the plaintiffs’ home, and therefore does not seem much less culpable than his codefend-ants. Certainly, Brown was not so dramatically less culpable that the district court abused its discretion when it declined to apportion attorney’s fees.
