It is true that some of the definitions given by the textbook writers, and found in the reports, limit jeopardy to a second prosecution after verdict by a jury; but the weight of authority, as well as decisions of this court, have sanctioned the rule that a person has been in jeopardy when he is regularly charged with a crime before a tribunal properly organized and competent to try him, certainly so after acquittal. Coleman v. Tennessee, 97 U. S. 509. Undoubtedly in those jurisdictions where a trial of one accused of crime can only be to a jury, and a verdict of acquittal or conviction must be by a jury, no legal jeopardy can attach until a jury has been called and charged with the deliverance of the accused. But, protection being against a second trial for the same offense, it is obvious that, where one has been tried before a competent tribunal having jurisdiction, he has been in jeopardy as much as he could have been in those tribunals where a jury is alone competent to convict or acquit. People v. Miner, 144 Illinois 308; State v. Bowen, 45 Minnesota 145; State v. Layne, 96 Tennessee 668.
