What William Giannetti describes is, on the surface at least, not a case of criminal justice ethics but of crime plain and simple. Though I shall eventually discuss some ethical issues, I must first focus on the crimes, in part because they lead to the ethical issues, but also because much in the story is less clear than it initially appears. On February 12, 1998, about 11 p.m., Philadelphia Police Captain James Brady, off duty, left a bar (apparently) drunk, got into his department-issued Grand Fury, and headed home. The moment his car entered the street he was guilty of driving under the influence of alcohol (DUI), a summary offense punishable by a fine of no more than $300, imprisonment for no more than ninety days, or both. (1) Brady had no justification or excuse for driving that night. He could have left his car at the bar and taken a cab instead. Cabs are easy to get in Philadelphia and well within the means of a police captain. A few blocks from the bar Brady collided with a parked car, causing substantial damage both to his car and to the Honda Civic he hit. He was, that is, involved in an accident. He left the scene of the accident almost immediately ("as soon as it was safe to do so"). He later claimed to have checked to make sure no one was injured, but there is no way to verify that he did and, given other facts, some reason to doubt it. He did not claim that he left his name and address on the Civic, that he called in the accident on his police radio, or that he did anything else others could verify. He seems to have behaved like a scared drunk, not like an experienced police officer. Whether he checked for injuries or not, he did not do what the law requires in case of a traffic accident. Where no one is injured, "hit and run" is a summary offense as serious as DUI. (2) Brady did, however, switch on his hazard lights and drive slowly after the accident, so slowly in fact that his driving caught the attention of Philadelphia police. Officer Colon pulled Brady over within a few blocks of the accident. Following standard procedure, Colon notified police radio that he was stopping a car. The stop was now part of the official record and Colon would have to turn in a report on it. Also following standard procedure, the dispatcher sent a backup, Officer Yatcilla. Meanwhile, Colon approached the stopped car. As he did, Brady got out of the car and identified himself with his captain's badge, not with his civilian driver's license. Why Brady chose to identify himself with his badge is not stated. The obvious inference, especially among police, is that he was asking for special treatment, the "professional courtesy" due a fellow officer. Colon may have responded as Brady expected. Seeing that Brady's walk was "wobbly," his speech "slurred," and his pants "wet around the inseam" (that is, the crotch), Colon radioed for a supervisor. There are two (more or less compatible) interpretations of this act. One is that Colon radioed for a supervisor because he did not want to take responsibility for charging a police captain with DUI. He might have reasoned, "when in doubt, call in a supervisor." The other interpretation is that Colon was merely following ordinary practice for DUI. Colon had neither the authority to make the final determination of drunkenness nor a way to test for blood alcohol. Since he had radioed in the stop, his only (legitimate) alternative to calling in a supervisor was to write a report explaining why he let the captain go. There could be no DUI charge without a blood alcohol test, and only a supervisor could authorize taking a motorist to a hospital for a test. (3) Within a few minutes, Lieutenant DiLacqua, a 25-year veteran of the force, arrived. He ordered Yatcilla to place the car against a pillar, radioed in an "auto accident" involving a "fixed object," and then ordered Colon to write a report indicating that Brady had swerved to avoid an oncoming car, mounted the sidewalk, and struck the pillar. …
