Just about every one of your posts are about Hebrews
The thread is about a black guy many believe got away with murder.
I would argue that the whites who defend blacks aren't stupid, just naïve. Many live in areas where there are no blacks or grew up in nice middle-class suburbs and can't imagine a people could be so disgusting.
I would also add that you never want to smile or show any type of friendliness around Blacks. It will be seen as softness and they'll look to take advantage of you. You never want to take your eyes off them either. You don't want to look directly at them, just out of the corner of your eye. So that they know that you see them. This approach will put the idea in their head that you're a cop. It helps if you're big and white.
