In other words, the mayor set the seal of his official approval upon the very practice which caused the injustice to Duffy. “Mugging” was all right, so long as you “mugged” the right persons. The situation thus outlined is one of more than passing interest. Whatever the merely political outcome may be, and it may be far-reaching, a sensitive point in our governmental nervous system has been touched and a condition uncovered that sooner or later must be diagnosed and cured. For the police _have_ no right to arrest and photograph a citizen unconvicted of crime, since it is contrary to law. And it is ridiculous to assert that the very guardians of the law may violate it so long as they do so judiciously and do not molest the Duffys. The trouble goes deeper than that. The truth is that we are up against that most delicate of situations, the concrete adjustment of a theoretical individual right to a practical necessity. The same difficulty has always existed and will always continue to exist whenever emergencies requiring prompt and decisive action arise or conditions obtain that must be handled effectively without too much discussion. It is easy while sitting on a piazza with your cigar to recognize the rights of your fellow-men, but if you were starving on the high seas in an open boat—! You may assert most vigorously the right of the citizen to immunity from arrest without legal cause, but if you saw a seedy character sneaking down a side street at three o’clock in the morning, his pockets bulging with jewelry and silver—! _Que voulez vous, m’sieu?_ Would you have the policeman on post insist on the fact that a burglary had been committed being established beyond peradventure before arresting the suspect, who in the meantime would undoubtedly escape? Of course, the worthy officer sometimes does this, but his conduct in that case becomes the subject of an investigation on the part of his superiors. In fact, the rules of the New York police department require him to arrest all persons carrying bags in the small hours who cannot give a satisfactory account of themselves. Yet there is no such thing under the laws of the State as a right “to arrest on suspicion.” No citizen may be arrested under the statutes unless a crime _has actually been committed_. Thus, the police regulations deliberately compel every officer either to violate the law or to be made the subject of charges for dereliction of duty. A confusing state of things, truly, to a man who wants to do his duty by himself and by his fellow-citizens!
