Thanks, ballen, and I agree that we have different perspectives. Arnisador and I disagree on many issues, but on this one, I understand where he's coming from.
There was a thread a while back talking about how dangerous a kick to the head is, and how it can crush a person's skull instantly. The person posting was an ER nurse (IIRC) and he used his anecdotal experience as evidence of how overwhelmingly deadly a kick to the head could be. But, when I found statistics, and pointed out that many, many people are struck in the head every day, all the time. They get bumps. They often rub some dirt in it (or whatever) and then take a few aspirin and forget about it. While a kick to the head CAN kill someone, it's actually quite unlikely. It's possible, but certainly not the rule. But as an ER nurse, this person came to have a skewed perspective. All he saw were the worst case scenario, and he saw them in a concentrated manner.
In the same way, I think cops run the risk of seeing mostly the worst, and frankly, I think you run a real risk of having a skewed outlook on some things. Kids, for example. Chances are, if you are dealing with kids, you're dealing with the worst of them. But I can guarantee you that there are plenty of kids who are just doing what they can to get through high school, and while they are surely being short sighted and making plenty of mistakes, most will turn out just fine.
Regarding the Obama stuff, I don't have any real comment to that other than that he's a black president in a polarized political climate. Anything he does is bound to piss some people off and let other people down. The two things you mention are completely unrelated to 99.9% of the country, but to you there's some kind of relationship.
