The problem with your theory is that President Obama has told schools not to do anything to a black child unless they can railroad a white child to keep things even.
That is what killed Trayvon. Instead of calling the law when they found him with stolen goods they called the Jewelry a recovery and not a theft. The hid the thief, and he went on to bigger things.
That is now the policy in schools. Let the blacks go , hang the white. We want better numbers. Crazy???? Hell yes it’s crazy, but look at the President, It’s his idea.
Something tells me they don’t have this problem in Singapore.
