I would say that for almost my entire career, the departments I've been associated with have been only marginally interested in defensive tactics training, and the main purpose of such training as has been scheduled is to limit liability for the department....
There was a brief renewed interest in hand-to-hand tactics in my dept when 3 of our officers attempted to arrest a career wine-o, and he messed up all 3 of them..It didnt last long as the Tazer was soon introduced and it became the answer for those that had no interest or desire to train...Perhaps the saddest thing I heard from one of these guys was "They shoulda dome that stuff when we were younger..I got got 4 years to I retire so I don't plan of getting into anything serious"..
