Hello,
my friend got into an argument with a guy (guy1) outside a bar. My friend left the argument and went towards his truck, when he got to his truck another guy(guy2) aggressively, in an attacking type of manner, ran up behind him yelling "why you going to your truck". Meanwhile Guy 1 ran away. My friend grabbed one of his tools from his truck and defended himself against guy2 with it, leaving the guy2 with wounds that require him to get staples and stitches to his head.
Guy2 at some point took the tool from my friend and hit my friend with it. Also, a bunch of guy2's friends jump on my friend and beat him...leaving him with wounds as well.
Guy2 told police that he was just trying to break up the argument between guy1 and my friend. My friend was arrested and charged with aggr. assault.
Isn't this self defence? Guy1 had already run off so what was guy2 breaking up? My friend says that he felt threatned by guy2 which is why he grabbed the tool in the first place.
