Let's say you're a black teenager in a rich white neighborhood. There's a cop that doesn't like you. He's received complaints from the neighbors about you, investigated them, and found it not be true. But he assumes you're a trouble maker. Now you have to be anxious about where you are seen, who you are with, what time you stay out at night ect. because the cops think you are trouble even if you never did anything illegal in the first place. If you were in that situation you would be afraid to do the things that are perfectly legal like play loud music just in case some racist neighbor calls the cops on you again for nothing. You just want your freedom and sense of security back. 

This is not my situation but I am in a situation I can;t talk about for fear of people's assumptions and the fact I don't want to start any trouble in case it would make things worse with Them. I can't trust any one I don't know not to assume things. Assumptions can ruin lives but they are taught that assuming is better than not and something bad happens. I haven't done anything wrong at all. I am afraid of being any more specific. 

Some one help? They'll never leave me alone because everybody trusts Them and They have the power.
