My wife used to be in this field and dealt with way more violent people than this guy, like there were many cases when she couldnt do anything but call the caps because the individual was in a violent mood and has a good 2 feet over her. But either way, you do your best to look out for these people and in no way is punching him in the face the appropriate response. Let us be honest, the reason the caretakers are trained in holds is to prevent people from getting hurt. So lets not go blaming the person who was a heart to work in the field of taking care of others. imagine if that was a senile old man and a nurse out trying to just do a simple stop at a gas station and this same scenario played out. there is no way the fathers response is appropriate, heck, he could have even faced jail time if he did more than just knock him down.
