A second police officer took the witness stand today to testify that illegal quotas for arrests, summons and stop and frisks drove his precinct's crime strategy.

Pedro Serrano worked in the same Bronx precinct as Officer Adhyl Polanco, who testified on Tuesday in the class action lawsuit challenging the city's stop and frisk campaign. The plaintiffs allege the campaign violated the civil rights of hundreds of thousands of New Yorkers. The city counters that stop follow crime trends.

Serrano spoke about his fear that the NYPD will retaliate against him for stepping forward and saying under oath what he has said in the precinct: that he rebelled against the quota policy for six years. He said stickers of rats have been placed on his locker.
