Police in Gun Searches Face Disbelief in Court
After listening carefully to the two policemen, the judge had a problem: He did not believe them.

The officers, who had stopped a man in the Bronx and found a .22-caliber pistol in his fanny pack, testified that they had several reasons to search him: He was loitering, sweating nervously and had a bulge under his jacket.

But the judge, John E. Sprizzo of United States District Court in Manhattan, concluded that the police had simply reached into the pack without cause, found the gun, then “tailored” testimony to justify the illegal search. “You can’t have open season on searches,” said Judge Sprizzo, who refused to allow the gun as evidence, prompting prosecutors to drop the case last May.

Yet for all his disapproval of what the police had done, the judge said he hated to make negative rulings about officers’ credibility. “I don’t like to jeopardize their career and all the rest of it,” he said.

He need not have worried. The Police Department never learned of his criticism, and the officers — like many others whose word has been called into question — faced no disciplinary action or inquiry.

Over the last six years, the police and prosecutors have cooperated in a broad effort that allows convicted felons found with a firearm to be tried in federal court, where sentences are much harsher than in state court. Officials say the initiative has taken hundreds of armed criminals off the street, mostly in the Bronx and Brooklyn, and turned some into informers who have helped solve more serious crimes.

But a closer look at those prosecutions reveals something that has not been trumpeted: more than 20 cases in which judges found police officers’ testimony to be unreliable, inconsistent, twisting the truth, or just plain false. The judges’ language was often withering: “patently incredible,” “riddled with exaggerations,” “unworthy of belief.”

The outrage usually stopped there. With few exceptions, judges did not ask prosecutors to determine whether the officers had broken the law, and prosecutors did not notify police authorities about the judges’ findings. The Police Department said it did not monitor the rulings and was aware of only one of them; after it learned about the cases recently from a reporter, a spokesman said the department would decide whether further review was needed....
