When the district attorney has been apprised that a crime has been committed, and that a certain person is the guilty party, he not infrequently allows the suspect to go his way under the careful watch of detectives, and thus often secures much new evidence against him. In this way it is sometimes established that the accused has endeavored to bribe the witnesses and to induce them to leave the State, while the whereabouts of stolen loot is often discovered. In most instances, however, the district attorney begins where the police leave off, and he merely supplements their labors and prepares for the actual trial itself. But the press he has always with him, and from the first moment after the crime up to the execution of the sentence or the liberation of the accused, the reporters dog his footsteps, sit on his doorstep, and deluge him with advice and information. Now a curious feature about the evidence "worked up" by reporters for their papers is that little of it materializes when the prosecutor wishes to make use of it. Of course, some reporters do excellent detective work, and there are one or two veterans attached to the criminal courts in New York City who, in addition to their literary capacities, are natural-born sleuths, and combine with a knowledge of criminal law, almost as extensive as that of a regular prosecutor, a resourcefulness and nerve that often win the case for whichever side they espouse. I have frequently found that these men knew more about the cases which I was prosecuting than I did myself, and a tip from them has more than once turned defeat into victory. But newspaper men, for one reason or another, are loath to testify, and usually make but poor witnesses. They feel that their motives will be questioned, and are naturally unwilling to put themselves in an equivocal position. The writer well remembers that in the Mabel Parker case, where the defendant, a young and pretty woman, had boasted of her forgeries before a roomful of reporters, it was impossible, when her trial was called, to find more than one of them who would testify--and he had practically to be dragged to the witness chair. In point of fact, if reporters made a practice of being witnesses it would probably hurt their business. But, however much "faked" news may be published, a prosecutor who did not listen to all the hints the press boys had to give would make a great mistake; and as allies and advisers they are often invaluable, for they can tell him where and how to get evidence of which otherwise he would never hear.
