Why don’t you really think why that is for yourself. And don’t try to be politically correct.
If you think that minorities (or women, for that matter) get the same justice as white men, then there's really no helping you.
And for what it's worth, being politically correct isn't a bad thing. It's simply not being an a-hole to people who are different than you because of their differences. Is it really so hard? But I suppose you want to go back to the good ole days of when America was "great" so you don't have to be thoughtful of other people and their feelings.
