Why are black ppl most likely to be called "UNRULY?"

Why i chose this topic? I chose this topic, because i am a big fan on proving people wrong. I, also chose it, because i'm black duhh of course so i know some things about being unruly not saying that i am. I'm so interested in learning and getting to know familiar opinions of others aspect of the situtation. What do you already know about the topic? So far i personally think that i know everything from my point, but i still need the opinions from others. I know that their are going to be opinions that i'm not in favor of such as "black children having troubled childhoods." Everybody knows that isn't true. So that's why you have me to prove all that b.s. wrong and let people know the truth behind all my facts that i'll support you with.
