On police body cams:

“We assumed that the justice system was eager to hold bad cops accountable and that all it was missing was the necessary evidence. It turns out the justice system is actually rather ambivalent about holding bad cops accountable, and so it handles additional evidence as halfheartedly as it handled all of the evidence it already had. A camera can allow you to see, but it can’t make you look.”
