I agree. CCW holders should have a course in de-escalation, and non confrontational encounters.
Then again, in a CCW stand your ground state you have no business shoving people down to the ground.
Many states no longer require training of any kind to carry a firearm. It'd be hard to retroactively require some now.
Proportional response means if I’ve been shoved to the ground without serious injury, and there is no attempt to follow up the attack, then I need to call the cops and report an assault. Arizona law doesn’t allow me to shoot someone in revenge for them knocking me down.
The threat needs to be ongoing for me to legally take action.
Flip side, the black guy committed a crime. But it looked to me like a past tense crime - commitTED.
