To all New Yorkers: You are currently NOT ENTITLED to see the methods and techniques taught at the NYPD academy.
Requests are being denied on these grounds: "Deniable records include records or portions thereof that: (e) are compiled for law enforcement purposes and which if disclosed would: iv. reveal criminal investigative techniques or procedures, except routine techniques and procedures;"
Police deal with violent criminals who have no regard for police life; in fact often they are explicitly against police. They're going to learn techniques appropriate for dealing with such people. Some of those techniques will be violent and resemble "military" tactics, but that's only because the military also deals with violent adversaries.
