I don't know, what evidence did you see that I didn't? Was it premeditated? If not, how would the guy videoing it know that he would be shot?You believe that murder charges were excessive for murdering someone? What do you think the charges should have been? And the driver was charged because he filmed the whole incident and did nothing to stop it. He literally filmed someone being murdered and then drove off like nothing happened.
Arbery wasn't jogging in the area, that's pure bull. The police had said he was a suspect in felony theft. From what I understand, you don't have to actually witness the theft in felony theft to make a citizens arrest. I'm certainly not going to argue that these were the smartest guys, but if you are having a lot of thefts in your neighborhood, people will start to take law into their own hands.
