A lot of facts here, but I should add that since cops are being actively trained for escalation and cruelty, and the fact that they are not to draw their weapon without an intent to kill, the fact is that no “less lethal” gadget or ammo is going to fix their behaviour. And neither is the Democrat answer of “more training” because the training they end up getting is more murder indoctrination.

You have to eliminate police unions, to start. End the 1033 program. Hell, defund the whole thing. Build a new society around what police ought to be doing, rather than merely projecting authority, violently crushing dissent, bashing minorities and poor people, and serving moneyed interests. The problems with police are deep rooted, systemic, and metastasised around a corrupt ideology.
