NYPD officer Adrian Schoolcraft's description of being taken in handcuffs to a psychiatric ward suggests the nation's largest police force could have a vindictive underbelly. He claims that cops risk retribution when they try, as he did, to blow the whistle on supervisors' faking of crime statistics to make the stats look better.

To back up his allegations, Schoolcraft made hundreds of hours of secret tapes while on duty — everything from roll calls to locker room chatter to bosses yelling at him. The tapes, along with medical records and other documents, were supplied to The Associated Press.
