If I remember, there was also a report from some LEO that seriously called into question Arbery’s mental judgment. In other words, not only was he a common street thug, but he was mentally challenged as well.
I have read that it is on the basis of his mental instability that he got out of serving time for his shoplifting conviction. I expect we will slowly get a more accurate picture of all the people and all the doings surrounding this incident.
