It is 100% relevant, because if your the person training you was worth a damn, they would have got though what to do if you actually have to use your weapon, why you should NEVER use your weapon on unless you are in direct danger, and how to deal with LEO after the fact if you have to use or draw your weapon.
If you're getting your ass beat in the kroger parking lot, guess what I'm not pulling my gun to help you buddy. I'll call 911, I'll tell the dude to back off, but I'm not the law and I'm not going to jail because someone else is an asshole.
So now you want to turn it on me huh? I too was very young and more stupid than most. Had a knife pulled on me in college at a party, that was fun. Had to defend myself in a bar fight after I was sucker punched with my backed turned as I was walking away from the conflict.
So yeah, been there, done that not impressed.
I've had work place violence too working the door at a bar, never had anything to defend myself but a stick or my mind, and I"m still here.
