The weapon, in seven trials out of ten, is the most important thing in it. By its means it can generally be demonstrated whether the shooting was accidental or intentionaland whether or not the killing was in self-defence.
Where this last plea is interposed it is usually made at once upon the arrest, the accused explaining to the police that he fired only to save his own life. In such a situation, where the killing is admitted, practically the entire preparation will centre upon the most minute tests to determine whether or not the shot was fired as the accused claims that it was. The writer can recall at least a dozen cases in his own experience where the story of the defendant, that the revolver was discharged in a hand-to-hand struggle, was conclusively disproved by experimenting with the weapon before the trial. There was one homicide in which a bullet perforated a felt cap and penetrated the forehead of the deceased. The defendant asserted that he was within three feet of his victim when he fired, and that the other was about to strike him with a bludgeon. A quantity of felt, of weight similar to that of the cap, was procured and the revolver discharged at it from varying distances. A microscopic examination showed that certain discolorations around the bullet-hole (claimed by the defence to be burns made by the powder) were, in fact, grease marks, and that the shot must have been fired from a distance of about fifteen feet. The defendant was convicted on his own story, supplemented by the evidence of the witness who made the tests.
The most obvious and first requirement is, as has been said, to find the direct witnesses to the facts surrounding the crime, commit their statements under oath to writing, so that they cannot later be denied or evaded, and make sure that these witnesses will not only hold no intercourse with the other side, but will be on hand when wanted. This last is not always an easy task, and various expedients often have to be resorted to, such as placing hostile witnesses under police surveillance, or in some cases in "houses of detention," and hiding others in out-of-the-way places, or supplying them with a bodyguard if violence is to be anticipated. When the proper time comes the favorable witnesses must be duly drilled or coached, which does not imply anything improper, but means merely that they must be instructed how to deliver their testimony, what answers are expected to certain questions, and what facts it is intended to elicit from them. Witnesses are often offended and run amuck because they are not given a chance upon the stand to tell the story of their lives. This must be guarded against and steps taken to have their statements given in such a way that they are audible and intelligible. A few lessons in elementary elocution are generally vitally necessary. The man with the bassoon voice must be tamed, and the birdlike old lady made to chirp more loudly. But all this is the self-evident preparation which must take place in every case, and while highly important is of far less interest than the development of the circumstantial evidence which is the next consideration of the district attorney.
The discovery and proper proof of minute facts which tend to demonstrate the guilt of an accused are the joy of the natural prosecutor, and he may in his enthusiasm spend many thousands of dollars on what seems, and often is, an immaterial matter. Youthful officials intrusted with the preparation of important cases often become unduly excited and forget that the taxpayers are paying the bills. The writer remembers sitting beside one of these enthusiasts during a celebrated trial. A certain woman witness had incidentally testified to a remote meeting with the deceased at which a certain other woman was alleged to have been present. The matter did not seem of much interest or importance, but the youth in question seized a yellow pad and excitedly wrote in blue pencil, "Find Birdie" (the other lady) "at any cost!" This he handed to a detective, who hastened importantly away. It is to be hoped that "Birdie" was found speedily and in an inexpensive manner.
When the case against Albert T. Patrick, later convicted of the murder of the aged William M. Rice, was in course of preparation, it was found desirable to show that Patrick had called up his accomplice on the telephone upon the night of the murder. Accordingly, the telephone company was compelled to examine several hundred thousand telephone slips to determine whether or not this had actually occurred. While the fact was established in the affirmative, the company now destroys its slips in order not to have to repeat the performance a second time.
Likewise, in the preparation of the Molineux case it became important to demonstrate that the accused had sent a letter under an assumed name ordering certain remedies. As a result, one of the employees of the patent-medicine company spent several months going over their old mail orders and comparing them with a certain sample, until at last the letter was unearthed. Of course, the district attorney had to pay for it, and it was probably worth what it cost to the prosecution, although Molineux's conviction was reversed by the Court of Appeals and he was acquitted upon his second trial.
The danger is, however, that a prosecutor who has an unlimited amount of money at his disposal may be led into expenditures which are hardly justified simply because he thinks they may help to secure a conviction. Nothing is easier than to waste money in this fashion, and public officials sometimes spend the county's money with considerably more freedom than they would their own under similar circumstances.
The legitimate expenses connected with the preparation of every important case are naturally large. For example, diagrams must be prepared, photographs taken of the place of the crime, witnesses compensated for their time and their expenses paid, and, most important of all, competent experts must be engaged. This leads us to an interesting aspect of the modern jury trial.
When no other defence to homicide is possible the claim of insanity is frequently interposed. Nothing is more confusing to the ordinary juryman than trying to determine the probative value of evidence touching unsoundness of mind, and the application thereto of the legal test of criminal responsibility. In point of fact, juries are hardly to be blamed for this, since the law itself is antiquated and the subject one abounding in difficulty. Unfortunately the opportunity for vague yet damaging testimony on the part of experts, the ease with which any desired opinion can be defended by a slight alteration in the hypothetical facts, and the practical impossibility of exposure, have been seized upon with avidity by a score or more of unscrupulous alienists who are prepared to sell their services to the highest bidder. These men are all the more dangerous because, clever students of mental disease and thorough masters of their subject as they are, they are able by adroit qualifications and skilful evasions to make half-truths seem as convincing as whole ones. They ask and receive large sums for their services, and their dishonest testimony must be met and refuted by the evidence of honest physicians, who, by virtue of their attainments, have a right to demand substantial fees. Even so, newspaper reports of the expense to the State of notorious trials are grossly exaggerated. The entire cost of the first Thaw trial to the County of New York was considerably less than twenty thousand dollars, and the second trial not more than half that amount. To the defence, however, it was a costly matter, as the recent schedules in bankruptcy of the defendant show. Therein it appears that one of his half-dozen counsel still claims as owing to him for his services on the first trial the modest sum of thirty-five thousand dollars. The cost of the whole defence was probably ten times that sum. Most of the money goes to the lawyers, and the experts take the remainder.
It goes without saying that both prosecutor and attorney for the defence must be masters of the subject involved. A trial for poisoning means an exhaustive study not only of analytic chemistry, but of practical medicine on the part of all the lawyers in the case, while a plea of insanity requires that, for the time being, the district attorney shall become an alienist, familiar with every aspect of paranoia, dementia praecox, and all other forms of mania. He must also reduce his knowledge to concrete, workable form, and be able to defeat opposing experts on their own ground. But such knowledge comes only by prayer and fastingor, perhaps, rather by months of hard and remorseless grind.
The writer once prosecuted a druggist who had, by mistake, filled a prescription for a one-fourth-grain pill of calomel with a one-fourth-grain pill of morphine. The baby for whom the pill was intended died in consequence. The defence was that the prescription had been properly filled, but that the child was the victim of various diseases, from acute gastritis to cerebro-spinal meningitis. In preparation the writer was compelled to spend four hours every evening for a week with three specialists, and became temporarily a minor expert on children's diseases. To-day he is forced to admit that he would not know a case of acute gastritis from one of mumps. But the druggist was convicted.
Yet it is not enough to prepare for the defence you believe the accused is going to interpose. A conscientious preparation means getting ready for any defence he may endeavor to put in. Just as the prudent general has an eye to every possible turn of the battle and has, if he can, re-enforcements on the march, so the prosecutor must be ready for anything, and readiest of all for the unexpected. He must not rest upon the belief that the other side will concede any fact, however clear it may seem. Some cases are lost simply because it never occurs to the district attorney that the accused will deny something which the State has twenty witnesses to prove. The twenty witnesses are, therefore, not summoned on the day of trial, the defendant does deny it, and as it is a case of word against word the accused gets the benefit of the doubt and, perhaps, is acquitted.
No case is properly prepared unless there is in the court-room every witness who knows anything about any aspect of the case. No one can foretell when the unimportant will become the vital. Most cases turn on an unconsidered point. A prosecutor once lost what seemed to him the clearest sort of a case. When it was all over, and the defendant had passed out of the courtroom rejoicing, he turned to the foreman and asked the reason for the verdict.
"Did you hear your chief witness say he was a carpenter?" inquired the foreman.
"Why, certainly," answered the district attorney,
"Did you hear me ask him what he paid for that ready-made pine door he claimed to be working on when he saw the assault?"
The prosecutor recalled the incident and nodded.
"Well, he said ten dollarsand I knew he was a liar. A door like that don't cost but four-fifty!"
It is, perhaps, too much to require a knowledge of carpentry on the part of a lawyer trying an assault case. Yet the juror was undoubtedly right in his deduction.
In a case where insanity is the defence, the State must dig up and have at hand every person it can find who knew the accused at any period of his career. He will probably claim that in his youth he was kicked in a game of foot-ball and fractured his skull, that later he fell into an elevator shaft and had concussion of the brain, or that he was hit on the head by a burglar. It is usually difficult, if not impossible, to disprove such assertions, but the prosecutor must be ready, if he can, to show that foot-ball was not invented until after the defendant had attained maturity, that it was some other man who fell down the elevator shaft, and to produce the burglar to deny that the assault occurred. Naturally, complete preparation for an important trial demands the presence of many witnesses who ultimately are not needed and who are never called. Probably in most such cases about half the witnesses do not testify at all. Most of what has been said relates to the preparation for trial of cases where the accused is already under arrest when the district attorney is called into the case. If this stage has not been reached the prosecutor may well be called upon to exercise some of the functions of a detective in the first instance.
A few years ago it was brought to the attention of the New York authorities that many blackmailing letters were being received bearing the name of "Lewis Jarvis." These were of a character to render the apprehension of the writer of them a matter of much importance. The letters directed that the replies be sent to a certain box in the New York post-office, but as the boxes are numerous and close together it seemed doubtful if "Lewis Jarvis" could be detected when he called for his mail. The district attorney, the police, and the post-office officials finally evolved the scheme of plugging the lock of "Lewis Jarvis's" box with a match. The scheme worked, for "Jarvis," finding that he could not use his key, went to the delivery window and asked for his mail. The very instant the letters reached his hand the gyves were upon the wrists of one of the best-known attorneys in the city.
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 testifyand 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.
