What is their "demographics"? Please define that. The only common trait between people, who committed some crimes and those, who are stopped is a color of the skin. If you disagree, tell me what are the other common traits.
Which brings another point. If people are stopped purely based on race, they are more likely to be presumed guilty based on race. A person accused of a crime can't afford proper defense. So it's basically all on the DA. This 50% statistics is skewed and feeds into further criminalization of race.
Agreed. I live in a suburb of Georgia and it is very desegregated. In my neighborhood we have asians, blacks, muslims, lesbians, gays and neo-nazis all living in harmony. It also consistently overwhelmingly votes Republican.
