Unfortunately, most people prefer to just distance themselves from the person rather than to confront them, their family or report them. They don’t want to make waves or they think it isn’t as serious as it truly is. I’d have definitely done what I could. Also, not much can be done until the person does something horrendous which is a very sad fact. There were signs and warnings but I don’t think anyone really knew what to do. The University that suspended him acted and suspended him but unfortunately, it wasn’t enough to stop this maniac in his tracks.
