Maybe I can help.
Im employed full time as a cop and I also am a tactics trainer at a police academy.
The police academy I went to was ultra-militaristic(modeled after marine corps basic training). We engaged in all sorts of high stress mind games when ever somebody in the class screwed up or whenever the instructors felt like it. There was plenty of screaming and yelling and all of that.
Do I personally feel that those aspects have ever helped me in my career? Not at all. They give a lot of reasons for that type of training. They include A.) it weeds out lesser motivated people(not really true in my experience...some real humps got by) B.) it teaches you to manage stressful situations which is obviously improtant in police work(I also disagree with this as playing mind games does not mimic any of the stresses I have faced on the job) or C.) it gives every cop a starting point, a new birth of sorts, and attaches some concept of sacrifice to the job which hoepfully cuts down on bad behavior later. While Im not crazy about some of the militaristic aspects, the academy should be a tough, trying ordeal in the sense that the physical and mental work is should be difficult.
Ideally, academy training should be focused on learning the job. It is way more complex and dangerous than it used to be. In most academies, their concept of physical training and tactical training at the recruit level is pretty bad and does not reflect the real world.
Despite my critique of the way business is done in a lot of academies, I certainly cant see much of basic training being done in the community. Like I said, there is sooooo much to be learned in the classroom, gym, practice field, and shooting range that something has to be sacrificed.
We did a couple of community outreach type things as recruits. They were nice PR, but to be quite frank, they didnt teach me shit. Most of us thought they were a complete waste of valuable time...much like daily uniform inspections lasting an hour or more(if somebody screwed up at these inspections, we sometimes spent 3 hours marching around and getting yelled at. What a waste).
In most places, police training is pretty bad if you know what really goes on. I dont think it should be further watered down by any attempt to integrate
basic police training into the community.
Once a cop is out on the street, then thats a different story alltogether. Trust me when I tell you that good cops learn to work in the community very quickly.
Feel free to PM me if you need anything you think I could help with.
