The future busts bad cops:

An NYPD detective will be charged today with lying on the witness stand about how he interrogated a teenage shooting suspect after the savvy 17-year-old captured the whole thing on his MP3 player, sources told The Post yesterday.

When Detective Christopher Perino of the 44the Precinct took the stand last year against Erik Crespo in Bronx court, he denied he asked the teen numerous questions during an interview about the shooting of a man in a Bronx elevator on Christmas Day 2005, sources said.

But when Crespo’s lawyer, Mark DeMarco, produced a DVD and transcript of the interview - as captured on the MP3 player - it became clear Perino was flat-out lying, sources said.

“[The teen] was recording the whole conversation and the detective never knew it,” one source told The Post. “He said, ‘No, no, no’ - and then everything he said he didn’t say was on the tape.”
