I like the way he chased them firing the whole time ! Not sure that qualifies as self defense, but hey, I LIKE IT ! That was bad shooting though if he did not kill them, the shots were close. I think as punishment to the old man he should get free range time at a local gun club, shooting lessons, lifetime supply of ammo, and a quality firearm of his choice. Dont mess with old farts, they have seen it all, done it all, have aches ,pains,arthritis, no teeth, impotence,diarhea,constipation, and bladder problems, sometimes all in the same day. They are pissed off, and have nothing to lose. I think they would make the best frontline soldiers!
