This is difficult.
Martyn Luther King said 'I have a dream that my four young children will one day live in a nation where they are not judged by the color of their skin, but by the content of their character'. I think we can all agree on that. I hope so, anyway.
He did not go on to say 'I believe that a black man should go off his medication, cause a ruckus in the local shop, push a deputy to the ground, punch the back of his head, and continue to resist arrest until he is stopped by force'. In that event he could expect dire and unforeseen consequences. Nothing riles the police more than having one of there own attacked, and with good reason. We all watch 'The Wire' and 'The Shield' for entertainment purposes, and not expect that real life will not include this particular scenario. Oprah Winfrey and the Rev Jesse Jackson might differ with that, but they are wrong.
I wish that those who would quarrel with me on this would spend a year serving as a US deputy, and see if that changes their mind somewhat. I haven't, but I can imagine. There's no point in hoping for a change in US gun culture, when let's face it, the majority of US gun owners would, if pushed, say that the main reason for that is 'fear of black people'. This might be to some extent illusory, but when you contemplate being confronted with a prison-hardened black person the size of Patrick Vieira and all that protects you, your wife, and your children is a fruit knife it's really hard not to concede they have a point.
Yes, there's due process in theory, but all that flies out the window in real life. I wish it wasn't that way, but unfortunately it is.
