_The Arraignment._--After the accused has been indicted the next step is to bring him before the court and arraign him. The charge is first read to him and he is directed to plead. If he pleads guilty, no further action is taken and the judge imposes the sentence. If he pleads not guilty, the trial proceeds. If he has no counsel to defend him, the court appoints some member of the local bar to act as his attorney, and the lawyer so designated is under a professional obligation to undertake the defense and do all in his power to clear him. In this way the murderer of President McKinley was enabled to have the benefit of counsel. Many writers on criminal law, indeed, contend that the state ought to employ regular public defenders for accused persons just as it employs public prosecutors, since it should be equally interested in seeing an innocent man acquitted as in seeing a guilty one convicted.[19] [19] In several instances provision has recently been made for such an officer; for example, in Los Angeles. _Selection of the Jury._--The next step is the impaneling of a jury of twelve persons to try the case. The law requires that the jury shall be selected from the community in which the offense was committed, in order that the accused may have the benefit of any good reputation which he may enjoy among his neighbors. The jury is chosen by lot from a list of persons qualified to perform jury service, and the jurymen are sworn to return a verdict according to the law and the evidence. Each side is allowed to "challenge," that is, ask the court to reject, any juror who has formed an opinion of the guilt or innocence of the accused or who is evidently prejudiced. In addition, each may reject a certain number of jurors "peremptorily," that is, without assigning a cause. _The Trial._--After the jury has been impaneled, the prosecuting attorney opens the trial by reciting the facts of the case and stating the evidence upon which he expects to establish the guilt of the accused, for the law presumes the prisoner to be innocent, and the burden of proof to show the contrary rests upon the state. The procedure of examining and cross-examining the witnesses is substantially the same as in the trial of civil cases. There are well-established rules in regard to the admissibility of evidence and the weight to be attached to it, and if the judge commits an error in admitting improper evidence or in excluding evidence that should have been admitted in the interests of the accused, the prisoner may, if convicted, have the verdict set aside by a higher court and a new trial granted him. One of the rules of procedure is that the jury must be satisfied beyond a reasonable doubt, from the evidence produced, that the accused is guilty.
