Seems we need CE (continuing ed) for police officers. The state (government) makes us private sector professionals do it, and we aren't doing life and death work (unless your a doctor), but yet most cops have little to no training or education after the police academy.
Start them with basic constitutional law. Seems so many forget (or never knew) what should be the basis for police work, not causing harm to citizens. That they aren't there to bark orders at people. They are to serve, to be inconvenienced by the public, who by the way are their employers. They forget that no job entitles them to convenience (when was the last time someone went out of their way to make YOUR job easier, thats right never!).
Yes, police work can be nasty and sometimes dangerous. But it gives no right to trample on other peoples rights.
