I'd rather have a gun.
To each his own.
I had a student once who was fascinated with guns and knives. He wanted me to teach him the stuff out of one of Mike Echanis' books. It looked just like yoseikan, except with a double-edged knife in each hand. With every move, he was slicing and dicing. My student wanted to be like Echanis and go down to Central America and kill folks.
I declined to help him work that stuff up and even stopped teaching for some time because of that.
He did go into the military, but I don't know what he did there. When he got out, he carried pistols with him all the time.
One night, at an ATM, a guy with a pistol came up and demanded his money. The guy pulled his own gun and shot the fellow in the leg. The guy went to the ground, but he fired up and shot my former student through the heart.
The former student ran some several steps and fell dead.
Well, who knows how we each will meet our fates? One thing for sure, we will meet it.
I'd rather have God's hand in mine at that time than to have a gun in my hand.
But that's just me.
