Camera Men/Producers Etc. stepping in

This is an interesting issue that has somewhat surrounded reality TV ever since the early Real World to the Road Rules and so on. Obviously the object at all time is the show but at the same time, this is reality TV, these are real people, and they're not actors. While the focus should be on the show, is somebody is fighting, or a relationship is abusive, or something along those lines, it should be the producer or camera mans obligation to step in. Sure ratings could go down, but at the same time at this point its not about the show and it's more than that. I mean if its a little shoving match, or a verbal arguement, obviously they should let the show play out but there is a point where they should feel they have to step in and occasionally you will see this in a show. The reverse of this is how possibly it can increase ratings as well. The producers can cut what they want and sometimes theyll include these parts where producers go in and more. Its frequently seen most likely in every Real world season at least once. But overall, there is a point where they do have to step into it just because it is "reality" and while some is scripted there are points where these are people and not actors.
