Posting videos is not a problem but there are approximate 700,0000 LEOs out there who did NOT beat up a blind guy.
A bit of balance would be nice.

I don't think anyone is implying that all cops do beat up blind guys. But all cops are not saints. There is a tiny minority of police who beat up blind guys, shoot fleeing suspects in the back, blow away 12 year olds in parks, and what have you. So sites like this do provide balance between those who say the police are never wrong and reality.
