Criminal Law—Conspiracy—Persons Joining After Formation.—Any one who, after a conspiracy is formed, knows of its existence and joins therein, becomes as much a party thereto, from that time, as if he had originally conspired.

Id.—Circumstantial Evidence.—A conspiracy may be proved by circumstantial evidence.

Id.—Sufficiency of Evidence to Sustain Conviction.—In this prosecution for conspiracy to violate a municipal ordinance forbidding public meetings or speeches within certain districts of the city, the verdict of guilty is supported by the evidence, although the defendant’s connection with the offense is established only by circumstantial evidence.

Id.—Evidence—Protests and Threats.—In such prosecution protests made against the passage of the ordinance, and threats to violate it in the event of its enactment, made by the defendants, are admissible in 'evidence.

Id.—Knowledge of Conspiracy—Evidence to Show.—Knowledge of the conspiracy may be shown by independent evidence, whether affecting both defendants or each separately; the question being, Did both parties have knowledge of the conspiracy actually formed to which they afterward became parties through a violation of the law 9

Id.-—Refusal of Motion to Strike Out Evidence.—The refusal to strike out the testimony of a witness with reference to discussions of plans at meetings to oppose the enactment of the ordinance is not erroneous. There can be no criticism of persons who earnestly and honestly oppose proposed legislation, taking all legitimate steps necessary in their opinion to prevent its enactment.

Id.—Appeal—Harmless Error.—The mere fact of error does not make out a prima facie ease for reversal which must be overcome by a clear showing that no injury could have resulted.

Id.—Misconduct of District Attorney—Objection—Review on Appeal.—It is essential, in order that misconduct of the district attorney be reviewed, that his acts be called to the attention of the court at the time, that an opportunity may be afforded to correct the abuse, and, if possible, avoid error and mistrial; an appellate court will not entertain an objection of this kind first made therein.

Id.—Error not Resulting in Miscarriage of Justice.—Reviewing courts are not permitted, where matters prejudicial in their character appear in the record, such as the misconduct of the district attorney, to reverse the judgment, unless from the entire record it appears that there has been a miscarriage of justice.

• Id.—Evidence of Protests and Threats—Cubing Admission.—In a trial for conspiracy to violate a municipal ordinance which forbids public meetings and speaking in certain districts of the city, error, if any, in admitting evidence of protests and threats made by the defendants before the passage of the ordinance, is not cured by the defendants offering evidence explanatory of their acts.
