If the officers referred to were superior to the mayor, he should have done what he could to coöperate with them, in dispersing the mob, and suppressing the riot, and on them would rest the responsibility for the measures they adopted; if they were not superior to him, then even he will not claim that he had a right to do nothing. All peace officers (and the military when called out to suppress a riot, is only a posse for the peace officers) are expected, and it is their duty, to coöperate for the purpose of keeping the peace. An officer, willing and anxious to do his duty, will never object to do what he can to enforce the law because some other officer or officers are trying to assist in the same object, even if they do not consult him, while one who is looking for some excuse for evading his duty is very apt to find one that will satisfy himself, although it may be satisfy no one else. Mayor McCarthy, at any time on the 19th day of July, at the head of a determined posse of fifty men, could have dispersed the strikers, and allowed trains to go out, and the trains once running, the strikers would have given up the contest. On the 20th of July, the mayor, with one hundred men, could have dispersed the crowd, and by the arrest of a few ringleaders broken the strength of the strike. These statements are made on the supposition that the mayor had been in earnest, and acted with the vigor that characterized several of the mayors who were called upon for the same duty in their respective cities at nearly the same time.
