I saw something similar to the incident described by Brennanfan, a few years back. A negro criminal walked up to a random white kid on broadway in manhattan and punched him in the eye. The kid was wearing glasses -- i recall the blood welling up and dripping from his eye. I didn't know the kid, it was a random act, but he probably lost his eye or suffered serious damage to his sight. The negro brute simply walked off with his gang, laughing, free, like a chimp in the jungle.
White people will not and cannot stop negroid violence, including the tens of thousands of black on white rapes every year. Back in the time of Thomas Jefferson, or even much later, the negro and his gang would have been tracked down and lynched for committing such violence.
Let's face it; today most whites are cowards. That's why america will become a third world country -- too many whites have lost their pride. They want equality...yadda yadda yadda; but the blacks want power and will use violence to get it. So far their strategy has been quite effective.
