To illustrate what a professional thief can accomplish with such a police officer, let it be supposed that the thief is happily married, as is sometimes the case, has a family, and wants to live in a certain town. The chief of police knows him, however, and can disgrace his family, if he is so inclined. The thief wants his family left alone, he takes a pride in it, so he visits the chief at "Headquarters," and they have a talk. "See here, chief," he says, "I'll promise you not to do any work in your town, if you'll promise to leave me and mine alone. Now, what's it going to cost me?" Sometimes it costs money, not necessarily handed over the desk, and not always to the chief personally, but in a manner that is satisfactory to all concerned. In other cases the matter is arranged without money, and the thief may possibly promise to "tip off" to the chief some well-known "professional" when he comes to town, so that the chief can get the benefit of an advertisement in the newspapers; they will say that such and such a man has been captured, "after a long and exciting chase ably conducted by our brilliant chief." The chase generally amounts to a quiet walk to the hotel or saloon where the visiting thief is quietly reading a newspaper or drinking a glass of beer, and the capture dwindles down to a request on the part of the chief or his officer that the man shall go to the "front office," which he does, wondering all the while who it was that "beefed" on him (told the chief who he was). A number of the "fly catches," as they are called in police parlance, which create so much comment in the press, can be explained in some such way as this. Meanwhile, however, what has become of the protected thief? He may keep his word, a number of thieves do, and commit no theft in the town where he is allowed to live; it depends on how much money he needs to meet his various expenses, how dear his family is to him, and what temptations he encounters. If he does break his word, however, and there are no hall-marks on his theft, by which it can be definitely traced to him, all he has to say, when asked by his protector as to who did it, is: "It must have been outside talent." In other words, he can "work" with almost absolute safety in the town, and the innocent public is paying taxes all the while for a police force that ought to be able to apprehend him. To prove that this case is not hypothetical but actual, I would say that I have recently been in at least two cities where I know that professional thieves live with impunity, for I saw as many as ten in each, and they were not afraid to do criminal work in either. The police of both places claimed that in giving the thieves a domicile they were protecting their towns, but any one who knows either city well is aware that professional crime is prevalent.
