Not saying I agree with the deployment, but as someone who was in this gun club this isn’t true at all and hasn’t been for some time. IIRC basic de-escalation was taught in recruit training.
I suspect that whatever training the military provides is more than what LAPD officers get. LAPD is talking a good game this time around but ABC broadcast footage of mounted LAPD officers trying to get their horses to stomp someone who was on the ground, prone, and not resisting.
