Except that saying "I use what the police use" is a great way to get portrayed as a sheep dog wannabe with fantasies of shooting brown people for fun.
Paul Harrell, who has been involved in one or two DGUs and had to take one to trial and was acquitted of the charges, rightly pointed out that anything someone does is going to be subject to scrutiny by a prosecutor. Look at the Grafton road rage shooting that happened - the fact that the shooter was in a polyamorous relationship came out on here.

lol and Ayoobisms etc are not really relevant in 90% of gun defense cases anyways. Guy has made a living yapping about corner cases. Lots of shitty people get plugged all the time by cops and citizens alike, most don’t get into the weeds of Ayoob glue fumes.
