What is the purpose of a gun? To kill/harm. Maybe it wasn't to kill humans, but animals to hunt or whatever, but it's still to kill.
To deter crime you say? How? Because the consequence of pulling a gun is such that someone gets hurt. So it's still because there's the fear of getting harmed.
No matter how you look at it, the gun is meant to harm.
To compare guns to cars, alcohol, etc. is foolish.
a gun is an inanimate object. the gun does what the PERSON holding it makes it do.
I have never killed or shot at a another human being.
I have hunted animals for food with one. I don't hunt very often though.
99.9% of the time I shoot a gun, I am shooting at paper.
It's all about the PERSON using the tool.
A knife is a tool. It can be used as a weapon or it can be used as a tool.
A hammer is a tool. It can be used as a weapon or it can be used as tool.
You have to worry about the PERSON using the tool, not the tool.
Banning something doesn't work anyway. As already stated, drugs are banned, prostitution is banned - but people are still using/selling/getting/etc.
There are things out there that kill more people than guns do anyway, but it's still legal. Cigarettes and alchohol and cars kill millions of people a year. No one is out there crying for them to be banned like they are for guns.
Cars are probably one of the most regulated objects we have today with registrations, tests, and we have so much stuff going for safety on these things, and billions of signs telling us how to drive, but there's still an ungodly amount of deaths by car each year. Whats the deal here?
here's an example you might understand (but probably not):
Should we ban computers or the internet? I mean, a few people use it to do bad stuff - hacking, theft, pedophilia, etc. I mean, that's a rel problem right? All our problems would be solved if we just got rid of and banned computers!
Oh wait, you mean the computer isn't an evil being controlling our minds making us do these things? you mean it's the person behind it doing these things?
but wait, if we ban the computers, they can't do that any more! wait, you mean this kind of stuff was going on BEFORE the computer was even invented? OMG! NO WAI! I don't believe you!
