I do agree that we have an issue with people recording everything.
However, after viewing the video I wouldn’t have put myself in the way of what was clearly a deranged savage and a horrific scene. I freely admit I wouldn’t be brave enough to risk my life and to leave my family behind as most probably wouldn’t either. It also protects the men who stepped in and fought the attacker off from any claims they acted inappropriately.
So in some ways, at least the victim has evidentiary support for the courts to put this horrific demon away.
