"They we're stupid for wanting to own guns?"
Short and sweet, YES.
"Mexicans and Columbians"
These nations do not produce or deal in weapons, either legally or illegally. The "market" you refer to is of a different nature.
In fact its the other way around. The US is the chief exporter of illegal weapons into these countries (France being #1 LEGAL exporter). BTW, its "Colombians" not "Columbians". US educational system fails once again *grin*
"But there's always the black market, and as long as that exists, and guns can be attained by criminals, who the hell are you to tell me that I can't defend myself?"
I'll try to dig up the statistics for you, but way more than half of all crimes in the us are commited with legally acquired weapons. That they were stolen or sold out to criminals by their legal owners is another matter though.. but the guns STILL came from legal sources. If weapons are banned, then ANYONE with a weapon will have to acquire them illegally, and that in itself is not only hard, but it will make it easier for the authorities to solve any crimes and probably close down the source of the murder weapon.
"In Oklahoma we have a thing called the "Make my day" law. No toejam. You break into someone's house, you can get shot. "
We have the same law in Colombia too. If you have your property fenced (as 99.9% of the homes are) and someone jumps into your yard you can shove a grenade on them if you want. My country's case is a perfect example of what a "let people have guns" law would do: Home owners are armed... nearly all of them in fact. Result: The robbers now dont come into your home to steal, they know they will be confronted; so they simply kill everyone and then steal.. and they come with MUCH heavier weaponry than the homeowner will ever have. Hell, before I left a home 10 blocks from where I lived was hit by machine gun and grenade fire before it was robbed. Luckily only the dogs were killed, the owners were out watching a movie in the theater.
Sad part is, we have much stricter gun ownership laws over there, its just that our police doesnt have any resources to control and enforce them... its nearly impossible to buy a gun legally. So you see, restriction is not the answer, and enforcement of those restrictions, when applied as in the case of the US where the police is effective, is not the solution either.
So from what I've seen, if people want a gun, they will get it. Black market, whatever. By denying gun ownership, in fact, by making it illegal to own guns you will make the average gun-totting crook, kid gangster, madman, etc, have a REAL hard time getting one... and keeping it if they ever get it.
The black market will be there yes... but tell me, how hard is it for you to get today, on the current black market, a thing that is strictly illegal? Say.. buy mustard gas or the components for it? Hmmm?
