@cicerone imposter,
No problem, and thanks for your participation in the discussion...
I happen to have grown up in the inner city and although I didn't succumb to the criminal lifestyle as many of my child hood friends did, I understand the injustices we all (both criminal and non-criminal alike) experienced. I've been "stopped and frisked" on my way home, even as I dressed appropriately with my work I.D badge on my person, and was still treated improperly.
Let me put it to you like this......
Working in a hospital and working alongside people of different backgrounds I see how certain people react to certain behaviors. A lot of nurses who grew up in Orange County, Manhattan Beach, or some affluent areas, I notice a lot of these folks tend to overreact when dealing with disgruntled African-Americans. For me, some of these reactions are merely people becoming voicetrous, but to them, they are being belligerent. I would take the similar approach towards white cops patrolling black areas. Because many of these officers don't take time to know the community to which they serve, any supposed attitude that appears belligerent they may overreact.
Because the United States hasn't gotten over the issue of racism and because police injustice is a reality, I strongly believe that cops ought to reflect the community to which they serve. I would say the same about the growing Hispanic community because since Los Angeles is predominantly latino, what does a white/black/Arab/etc cop know about Latino culture aside from food? Maybe I'm wrong in my thinking but I see this to be true.
