The "if they're going to kill, they'll kill" argument is rather amusing. It seems the people using this statement are trying to say "well, we might as well let them have guns, they'll do it anyway" - what sense is there in giving these people who are "likely to kill" the methods to do it? Utter idiocy. How do you commit a massacre in a school by shooting students if you don't have a gun to shoot them? You can't.
I'd hate to see a society where we have to live not knowing whether the person next to you is carrying a gun. True, it's almost impossible to know that now - but with the current restrictions, it's unlikely - however, allowing it to be freely attainable is detestable.
Guns should only be carried by people who are authorised to use them. Police. Army. Whatever. Not by average joe number 23331.
You all go on about "we should allow people to have guns" in order to protect ourselves from others who have guns. We wouldn't need to if they didn't have guns at all! If they weren't available to civilians, we wouldn't be able to!
The pro-gun lobby are doing the same thing the Cold War did. "If you're gonna have nukes, then we'll have nukes." "Nuke us and we'll nuke you." As some sort of crazy deterrent. How about getting rid of all nukes? That's a much sensible path.
You people pride yourselves in logic. I suggest you start using it.
Either that or go die, don't ruin this world for my children.
