even Sam Hyde brought this up. your kinda fucked shooting in self defense in the USA. and anything you used for it is going in an evidence locker forever after that sadly. Their is not a win self defense situation or even in the cases like these
1. don't live in a shithole or around shitholes (I'm in STL... this one isn't easy)
2. if you see someone being retarded or aggressive avoid them and walk away (prime example, someone tried to speed around me recently but got cut off and blamed me, they started following me in their car, do you think I stopped to confront them?). Don't argue with people in public about stupid shit, literally just turn around and leave, they are literal goy cattle, who gives a fuck what they think/do (avoid nigger moments).
3. Don't try to be a hero/john wick. Having a gun doesn't make you a hero, don't act like it does. (realistically if you do end up shooting someone/something it's likely going to be a crackhead who lost it or an injured animal on the side of the road.. very heroic)
4. If you can record a video in any way, do it. it may be the only thing that gets you off.
I don't like all the metagaming about CCWing, and I hate mossad ayoob but his advice "if you aren't sure it will be a clean shoot, don't shoot" is pretty good advice that will keep most people out of doing something retarded. Not that you really have time to thing about that when getting chased by a crackehead, but idk.
This really depends on the micro-political climate you live in and the details of the shooting. There are some cut and dry self defense shooting cases where the shooter is barely detained. Hell you have police chiefs giving shoutouts sometimes.
This is something to consider..... which is why i carry faggot guns exclusively

I used to live in libshit retard area, a guy shot a teen in a shiesty at 2 AM after exiting a bar, the teen was running up on him. The PD didn't press charges, you legally can run up on people in a shiesty at 2AM, but if someone reasonably fears for their life ¯\_(ツ)_/¯ oopsie you might get popped.
But There have been guys in Cali who've shot people running into their homes with machetes and they get everything confiscated

again, don't live in a shithole is the best advice.
I'm wary of all of these CCW insurance places, they all seem like a scam/great way to burn a few hundred bucks a year.
