KKK says it will kill protesters and Anonymous gets involved

Anonymous hacked and took down KKK websites and posted personal information (names, place of work, home addresses, etc.) of KKK members.

Normally I would say it's an infringement on free speech but in this case I think it's just fine. When the KKK takes off their hoods they can speak all they want to. Until then they are cowards.

What bugs me is the absolute assumption that the Grand Jury is going to make the citizens of Ferguson so angry that they will want to riot after the decision. Are they really that sure the cop is going to get off this time?
If they can be that sure than that's the real problem with the system. I also suspect he'll be excused for shooting a man with his hands in the air multiple times and I'm not black. I hope I'm wrong. This decision is taking a very long time to make.
