I will admit that with 2 exceptions (1 while I was in high school and 1 while i ws in college) I have never had a run in with an unprofessional cop. So most of them are good people just trying to do a tough job. But they can't protect the bad apples because that casts a negative light on all cops and makes their job much harder. When it's on video and its obvious they are wrong something has to be done to both show the public that the rules apply to everyone and so cops know that their job is to resolve all matters peacefully.
The worst that ever happened to me is getting stopped for speeding in OK, with CA licence plates. He came to my open window and said "Do you speak English!!" With my British accent I replied: "I speak perfect English, you don't by the way, you speak American." That was probably not the smartest thing to do, he promptly ordered me out the car, grabbed me by the arm, walked me to his car, put me in the passenger seat and wrote the ticket.
Arch, while I agree with you that excessive force was used in these two instances, while other methods such as Tasers, or negotiating a bit more in the NY incident could have been better, this is a complex scenario. I really believe it is highly unlikely that anyone who complies with a LEO's requests will be forcefully handled to the point where there is injury. Be arrogant, resist arrest and things can go South rapidly. The challenge is that we have three things to achieve here. The first is giving the Police force the confidence that they have the authority to maintain law, order and peace among the community while operating under the magnifying glass. The second is to maintain order among troubled communities. The third is to gain trust and RESPECT for the authorities operating in troubled communities.
I believe there is strong support for both sides, the police victims and the police themselves. I believe Wilson has resigned with no severance, but charity funds have already collected over $1 million for him, showing how strong the support is out there.
If we take the side of Brown, it will definitely affect the confidence of the Police force in how to do their extremely difficult job safely.
If we take the side of Wilson, we have an upset community, looting riots.
I don't have the right to judge, but my bias tends to steer away from folks who burn, riot and steal, or sell stuff illegally on the sidewalk and then resist requests from the authorities. The reason for this is that I was raised to respect older people and people with authority, whether this was my parents, my school/college teachers, or the police. I was taught as a child to respect them and obey them, irrespective of whether it made me happy or sad.
