No matter what laws you make, someone somewhere sometime is going to decide to break them. In any given society, someone will eventually get mad and try to murder someone else, or steal something, or just be a general nuisance. These people need to be dealt with. Being black, or homeless, or poor should not be a crime and should definitely not be a death sentence, but those aren't the only laws that police enforce. Try not to be loudly hyperbolic and people might actually take you seriously enough to consider your ideas.
