One of my gang mates asked for help at piers because he was getting robbed. I arrived at piers to see one of the armed men kill my gang mate and my other gang mate escaped. The one who escaped explained to me how the men were robbing them and had just killed one of my gang mates so I scanned the hill for snipers and saw at least 2 armed snipers on the hill, I dont use the mouse scroll wheel to meta-game peoples names so as far as I was concerned you were part of the same group. Due to them being very close and also being in the direction of where the shots were coming from I opened fire on them and killed them. I see now in this video they may not have been involved in the robbery but non the less they were in the vicinity of the fight and had fully modded guns. If they had no intention of being involved in a gun fight the best option would have been to have holstered weapons. Sadly they rolled in to an active fight.
