When you don’t want to cooperate with or participate in the justice system, all kinds of awful and unjust things just sit there, and everyone knows it.
It's pathetic that the police can't get any cooperation in a case like this where the victims and the perps were black, but if the perps were white (especially white police officers) there would be witnesses crawling out of holes all over the place and even lying about the facts of the case.
Personally, I think I'll file this one in the "My give a sh!t is broken" category.
