> But I really dislike the idea that "people of colour" are apparently all miscreants, and therefore always doing wrong things, and thus are always being charged.
That's not the idea.
The idea is that people of color ar disproportionately targeted, compared to others in similar objective circumstances, for traffic stops, and this overlaps considerably with the use of certain minor traffic offenses as pretexts to look for excuses for arrest on other charges, so that bias in traffic stops is foundational to broader enforcement biases.
There's plenty of individual local jurisdictions and larger areas where this has been studied and proven out (and sonetimes been part of the basis of US DOJ action against the offending local jurisdiction), though I’m not familiar with evidence related to SF specifically.
