The mcmichaels are and must rely on the GA law at the time which allowed citizen arrest. GA repealed the law last year but it was in effect at the time. Under that law a person may make a citizen arrest if they witnessed a crime firsthand or had direct knowledge of the crime. The father and son didn’t witness anything according to their own statements which are on body cam video. And Arbery didn’t take anything and the house under construction was posted keep out and Arbery was never trespassed from there, so even a two bit trespass isn’t available either. They thought Arbery may have taken something months ago (zero evidence of that)
And while rittenhouse ran from all three attackers (and others) the mcmichaels pursued Arbery and at the end were far ahead of Arbery, the son got out of the truck with a shotgun, then went around the truck and met Arbery in front of the truck.
Rittenhouse is as innocent as it gets, the nitwits in GA really have no legitimate defense. They were the aggressor through the entire thing
