Perhaps if more of us used the Second Amendment solution, scenes like this would disappear from the landcape. As the folks in NYC found out after Crown Hgts., you have no 'right' to expect police protection in such circumstaces. IOW, you're on your own.
I was thinking about the Crown Heights riot too, when I heard this story.
If Yankel Rosenbaum HAD pulled out a weapon and bust a cap in the head of any of his attackers that night, I'd lay odds that he'd have been indicted for murder and sued by the creep's family.
Isn't that how these scenarios play out?
