What a strange story. I would almost bet the “big gun” might have been fake or a toy. Why would he not return fire after threatening to kill everyone and waving it around? Father better lawyer up big time!
Shouldn’t matter if it was toy or not.
A cop shot and killed a 13 year old carrying a toy rifle and was exonerated...

While I vehemently agree that the father should lawyer-up, I don't see that he is in trouble if the gun proves to be a fake of some kind. There is no way for him to have known that or even suspected it.
The weakness I see in the incident, which is not great I think, is that he apparently closed ground on the attacker, exposing himself to more risk. He might reasonable do this if he fears that the attacker might hurt someone else.
It is rather impressive that the guy started out with a knife and was able to retrieve a handgun while still in the presence of the attacker. That circumstance seems unlikely.
He had no huevos. If he did he would have opened fire to begin with.
handgun – “ TEC-9 semiautomatic” – possibly jammed?
