From 2014 through Q1 2020, Black pple in SF were 4.4 times more likely to be stopped while driving than whites. These data are one reason why, in early 2020, I implemented a policy not to charge cases of contraband found during racist, pretextual stops.https://sfist.com/2020/09/15/data-shows-black-people-pulled-over-by-sf-cops-disproportionately/ …
In San Diego researchers found similar results - and that Black drivers were arrested and jailed more even though they had fewer violations, infractions, contraband, weapons etc. And more and heavier forms of violence used against them by police. http://Policescorecard.org/sandiego
