Racism is thinking one race is superior and act on that. Nothing can change that. If we are dealing with another phenomenon we should find another name for it.
The belief that blacks in the US are more likely to commit a crime than nonblacks is similar to the belief that men are more likely to commit a crime than women. Blacks and men are disproportionally more likely than non-blacks and women to be stopped by police. Nobody finds the latter discriminatory although the disproportion rate is far higher there. Both beliefs are rooted in our screening of the environment we are living in. Both beliefs are stereotypical and biased but that's all they are. Having lived in Philly in the past 7 years, the assailant/suspect in every single alert I have received on my phone from the university police about a crime, from theft to armed robbery and aggravated assault, is a black man. Now I'm coming from another country, and I see myself as very empathic towards the poor and marginalized and vulnerable. When walking home at night in an uncrowded street though, I feel much more threatened when I see a black than a white person coming towards me, a lot more threatened when I see a man than a woman. I am stereotyping, and police do that too. There are two differences though: one, the police have screened the environment a lot more than me and have had more exposure to what's happening out there (doesn't mean there are no racist cops but the % is probably proportional to the % of racist people in the country), and two, while my stereotyping will make me cross the street or be more alert about a potential threat, Police's stereotyping can take an innocent person's life, so we should use incidents like this to demand reform because any life that's taken unjustifiably is worth our attention, sympathy and call for a change.
