Actually, blacks being arrested or questioned are equally disrespectful to black police officers, too. It’s all part of a weird sense of privilege or specialness that somehow has been instilled in this self-defined “militant black” group, making them feel that ordinary law and ordinary procedures don’t apply to them.
Being aggressive or hostile to the police and even to the law itself is somehow “sticking it to the man.” I think this attitude is one that is a serious problem among young blacks and has really held back their progress in joining the larger society.
I've seen a real increase in hostile behavior since Obama got the nomination. Not just to police but toward whites in general.
