Raz, you have some serious misunderstanding of open carry laws. You get to carry it in a holster, NOT your hand. If LE is pointing a weapon at you, demanding that you drop the gun, you ARE obligated to drop it on command. Mr Scott absolutely does not have the right of self protection if he was misreading the situation. If you draw a weapon in self defense you are required to be right. Add to that you are prohibited from possession of a firearm if under the influence or a drug.  

Another flaw in your argument, is you point that the wife would not permit him to carry under his condition. Unless you have a history with the wife, that statement is pure conjecture and 100% worthless.
