What about the cops letting a hundred speeders through residential neighborhoods go in lieu of making sure they get the poor Mexican with semi-illegally tinted windows just trying to get to work (and actual work at that)?
The only way society changes is if cops start harassing the Karens and Brodies in the rich neighborhoods the exact same way they do with blacks and mexicans in the hood. Just like the War on Drugs - change only happens once the insulated part of society freaks out that it could actually happen to them.
The question "What are you doing in this neighborhood?" and variations of it should be illegal and automatically considered discrimination.
