The answer is, "Depending on what was happening", the same criteria would apply either way. First I would have to know what was going on and then decide what to do. There are some that claim that they could tell immediately and would jump right in. That is not me, before I help either one I have to know who is the BG, who is the GG and what is about to be the end result. In one of the McDonald's videos the girl was being beaten and some fellow broke it up. The two girls doing the beating walked away and so did everyone else leaving the beaten girl just lying there. The two girls came back for more whipping. If someone had just gone to help the girl on the floor while the other two were away they would not have returned. That was the stupid part of the video.
