Tray tray was not the same in my opinion. A VERY important distinction was that the 'vigilantes' were an organized group with the blessing of the neighborhood. Seems a minor distinction but it is not. The home owners gave them permission to confront trespassers/thugs.
They were an organized group that patrolled the area at the behest of home owners. When trey trey was confronted for being where he should not be? he attacked. He actually had the guy down on the ground and it was a kill or be killed situation. The 'vigilante' in this case had the blessing of the homeowner. Not sure the Georgia thing went down like that.
