Are you serious? I can't prove anything like that beyond a shadow of a doubt. I even admitted it is a general statement and a general statement, by definition, has exceptions and doesn't apply everywhere. If you bother reading you will see where I even admitted that. I also used the word "tend" several times. Now if you're having difficulty understanding that word allow me to give you the meaning of it:

Tend: regularly or frequently behave in a particular way or have a certain characteristic / be liable to possess or display (a particular characteristic).

Note the word tend is not an absolute. But since you seem to having some sort of issue I guess that I will just bow to your superior knowledge despite the fact that several members, including myself, have some actual experience in the matter while you openly admit you have none. But as is often the case, those with little or no experience seem to think they are experts so I bow down to you and accept the fact that I don't know what the heck I'm talking about.

Now I throw your challenge back at you: Prove to me, beyond a shadow of a doubt that a higher amount of ammo available DOES NOT lead to people shooting uncontrollably. Give me the proof in the same way you demand the proof. Can't do it can you?
