Whatever Happened to Justice?

In the constitution it says, "All men are created equal."  This means that no man should get punished unjustly while another man in the same circumstance wouldn't get punished at all.  It also means that no man is greater then others, and no one should have to bow to someone else.  Sometimes black people get punished unjustly or aren't treated like they should be, and sometimes it's the other way around with white people getting the short end of the stick.  This should not be!
