Billyblobber...I agree with several of your observations. And it is true, every area is different in demographics and crime levels. I worked in an area that was a mix of very prosperous professionals and a large Hispanic population. We had a fairly active gang scene, so we typically went from a "barking dog" call to a "man with a gun" call. I saw my fair share of youth oriented crime, and dealt with all types of ethnicities. As a rookie cop, I was trained to treat everyone the same, without consideration of race. What I did see in my years on the job was the jaded attitude officers could develop over time. This was not towards a specific race, but rather a "type". The type included black gang members, Hispanic gang members and white supremacists. The common thread tying them all together was not color but behavior. It is very difficult to not become jaded when dealing with these idiots...where it becomes problematic is when one fails to differentiate between the thug and the law abiding citizen. I think this is what happens in many lower socio-economic areas, and thus the negative interaction with the local police.
If you haven't done so yet Billy, I would recommend you do a ride along with a busy department. It may reinforce your opinions, or it may give you an additional perspective on police officers. It can be a real eye opener, and it will be unscripted.
