Civil-liberties lawyers yesterday attacked the credibility of three cops who testified about arrests they made under the NYPD’s stop-and-frisk program and urged a judge to order reforms including a review of every trespassing stop in The Bronx.

Lawyer Christopher Dunn said contradictions between the cops’ testimony and their written reports and memo-book logs put lie to the city’s claim that they had acted within the law.

“From our perspective, putting the police officers on the stand didn’t help the city, it helped us,” he said.

During closing arguments in a case challenging stop-and-frisk, Dunn outlined a series of proposed measures to prevent alleged abuse of tactics.
