Whether we should have hate crimes at all, or just very heavy gang enhancers to the basic charge of aggravated assault is another topic. But, a 20 on 1 beatdown isn't just a neighborhood disagreement out of hand.
I heard that they were shouting
“Random beatdown! Random beatdown!”
Imagine if a crowd of 20 whites came after a black guy on his own property and beat him nearly to death. Think THAT would be a hate crime?
