I'd sure like to know what empirical research you've seen that leads you to your conclusions....
Which conclusions are those?
Clear that the boots on the ground have a tough gig? I was raised by a LEO.
Too many suits in police, and nearly all other large organizations who are detached from the work being done? I live in the world, and actually work jobs with several major corporations.
The idea that the concept of "crime prevention" implies scrutinizing citizens? It's not an observation to begin with. It's an understanding of an implication of ideas.
The idea that the mindset of police states are that the police are overlords over the people? I read history.
That NYPD has crazy unchecked power compared to ATF? I was born in NY state, and lived NYC for several years.
Looks like we have another one, guys. I swear its like playing whack-a-mole.
Well, to me "Crime prevention" means getting cops on foot in the business areas of the jurisdiction, it means attending public meetings with a note pad to get a feel for the priorities of the community, it means identifying the days of the week, times of day and the locations where the most serious crimes are committed and flooding those areas with uniformed patrol officer in vehicles, getting them out of their cars and having them approach, and talk to anyone out on the street they may find. People don't have to talk to cops under these circumstances, but those who do may be given a quick pat down for the safety of the officer and the citizen. There is a place for police intel and most of that kind of work is done through surveillance and analysis is done back in the office however, what you seem to be talking about is out of control federal law enforcement endangering individual liberties which is a whole different ball game from municipal, county and state Law Enforcement.
As far as "too many suits" is concerned, I'm sure your dad told you that most of the slings, arrows, and spears in Law Enforcement are behind the street cop, and this is just the part of the profession that the guys on the street have to deal with every day on the job.
