The crowd was not armed and I'm pretty sure they weren't shouting death threats either (although there were some threats made earlier). A lot of people have made plainly false statements of fact on this thread. You are one of them.
These kids were also well-known to be a gang of toughs called 'The Blackout Club' who directed hostile action against blacks who lived in their community.
I'm suspicious of your defense of these animals when you don't seem to know the facts. I think I know why.
