The person who made the recording gave it this week to Officer Schoolcraft’s lawyer, Jon L. Norinsberg, in an effort to show that Officer Schoolcraft, who has been suspended from the force, was not alone.

“He wanted to do anything in his power to support Schoolcraft, and I think this is his way of corroborating Schoolcraft’s allegations,” said Mr. Norinsberg, who said the new recordings would be used as evidence in his case. “It is evidence the quota system is ongoing. Subsequent to the public revelations that have taken place, it’s business as usual in the N.Y.P.D.”

At one point in the new tapes, Inspector Mauriello introduced Captain Perez, who the supervisor said was second in command, as someone who “wants his summonses.”

“They’re counting seat belts and cellphones; they’re counting double parkers and bus stops,” Captain Perez said, referring to types of low-level summonses typically tracked by the department’s TrafficStat program. “If day tours contributed with five seat belts and five cellphones a week, five double-parkers and five bus stops a week, O.K.

“Your goal is five in each of these categories, not a difficult task to accomplish on Monday,” he added. “If it’s not accomplished by Monday, you’ve got to follow up with it on Tuesday. But there’s no reason it can’t be done by Thursday. So whatever I get by Friday, Saturday, Sunday is gravy. I’m not looking to break records here, but there is no reason we should be losing this number by 30 a week.”

Losing by 30 a week refers to a decline in the activity as reflected in departmental CompStat reports, which tally the weekly summons totals and the year-to-date totals for every command, said the person who made the recording. He spoke on the condition of anonymity for fear of retaliation and of risking his standing with people in the department.

Asked if the conversations were evidence of a quota, he said, “Absolutely,” adding that he had seen evidence of it in several boroughs.
