Are you saying the standard doesn't go both ways? I'm sure you could find examples of white on black crimes that didn't go national. These things happen everyday, it really just comes down to luck and how touching/sad the story is to get coverage.
Mate you need to get some type of life. This is racism thing you got going on isn't going to make your life better. And you sure as hell aren't going to change the world by posting it on NB.
