they didn’t have to be told anything, the morons video tapped the whole thing.
Chasing the victim down in their trucks, cutting him off, jumping out and pointing a gun at him.
All of this was shown to a jury that unanimously agreed that these guys murdered that guy.
You have presumably watched the video you mentioned. In it you can clearly see they are not chasing him. The stupid SOB runs at and attacks the man with the shotgun and he gets shot. This is what is supposed to happen if you attack a man with a shotgun.
Arbery is not the "victim." He is the piece of sh*t that instigated the whole thing, up to and including his own death. The victims are the people who have just been railroaded by our sh*tty incompetent/corrupt legal system.
