This!
Also I know its easy to lose your cool especially over a lot of money like that, but you need to think before acting still, I know your intentions were getting this guy who ripped you off but running in public with a loaded gun is just a terrible idea, I mean whats to say while chasing him you trip and fall and the gun goes off and you accidently shoot a young kid walking with a parent or something. Not trying to be an asshole but you have to look at the big picture before running around with a loaded gun. Just wooping that idiots ass would have been a lot safer/smarter and probably a lot more satisfying IMO.
Either way good luck with court hopefully it goes well and you learn in case it happens again.
