Police lie in court with impunity, yet juries almost always take their word over defendants’. The New York Times writes:
In this era of mass incarceration, the police shouldn’t be trusted any more than any other witness, perhaps less so.
That may sound harsh, but numerous law enforcement officials have put the matter more bluntly. Peter Keane, a former San Francisco Police commissioner, wrote an article in The San Francisco Chronicle decrying a police culture that treats lying as the norm:
“Police officer perjury in court to justify illegal dope searches is commonplace. One of the dirty little not-so-secret secrets of the criminal justice system is undercover narcotics officers intentionally lying under oath…it is the routine way of doing business in courtrooms everywhere in America.”
The New York City Police Department is not exempt from this critique. In 2011, hundreds of drug cases were dismissed after several police officers were accused of mishandling evidence.
