We're probably mostly in agreement, even if we lean slightly different directions on some of the issues. For example, I can't think of any legitimate MRAP uses by local police either (although if anyone can point our a realistic use case, I'd definitely like to hear it).
I completely agree that the police should be part of the community they work in and not some military-like third-party authority force. And because of that it presents an issue when the police look like a pseudo-military. However, I don't think in most cases police look like this, although I might be wrong.
Body armor is a tough call. Just yesterday a Texas police chief was killed making a routine traffic stop, and it's understandable why officers feel constantly threatened. As far as I could find, about 65 police officers die in the line of duty each year. My first reaction is that that is pretty low, perhaps policing isn't as dangerous as one would think, but I'd need to look into it a lot more before drawing any real conclusions. It's quite possible the relatively low death toll is a result of more aggressive policing, but it could also indicate that aggressive policing isn't needed.
