Instead of punishing white people it would be better to find all the reasons why minorities (especially black people) have such a strong representation in prison.
I've actually studied this topic from both sides. How minorities (latino and blacks) raise their children contributes to this. Then there actual racial crime patterns. The added culture that latinos and blacks have of being afrid of encountering a corrupt cop or a cop who is use to a racial crime pattern (because cops see them a lot) creates an atmosphere that's easily missunderstood when someone is blatantly doing something wrong.
The media's Ghetto culture is seen as a way to empower ourselves (i'm latino) but it's actually a culture of criminalization. If someone dose something wrong then they should go to jail, and racial crime patterns exist, blacks make up an alarming amount of the prison representation with latinos close behind. I also know black friends who are followed by police.
It's the "natural growth" style parenting that latino and blacks do instead of tending to the child's mind early on that doesn't raise the maturity of these two minorities leaving for greater missunderstanding and frustration, add the african american high blood pressure or lack of mature family environment and clearly minorities will have difficulties with police.
So class, family structure, media influence, cultural child parenting, genetic variables and the psychological connotation of police is why minorities can have problems with this confrontation.
I once went into a store and me and my brother and cousin started walking around the store, since we didn't buy anything and we we're kids in a liquor store the manager told us to leave. I wasn't drinking at 14 but the connotation was obvious to him.
TL;DR: Blaming white people for their reputation isn't a solution. there are a few factors that minorities need to answer in their own parenting style, their cultural and psychological fear of police, and the seemily harmless media, gangs or ghetto subcultures they let their kids enjoy. It's disgustingly common for latino children to develop small gangs and they harass the children that don't join.
