Thinking about developments in weapons, you would think that black powder weapons would be generally legal as they are almost completely irrelevant now (figure it'd be less hassle to harm someone with a nerf gun than those things) but what about the new electronic sight & trigger they're making in texas where you can mark your target and the sight will almost take over the aiming bit, you just squeeze the trigger and it'll fire when you point it the right way?
To take it to extremes, when we develop man portable laser weapons, should they be legal/illegal? What about plasma?
I think that if you had to start from scratch with gun control in an area it would look very different from most approaches in use today. Even Britain's laws confuse me. You can't have a gun except one which works wonders at urban warfare (2 shots aside) and can be modified by a trained gorilla to be concealable. I have to wonder if 10 gauge is legal. What about 4?
Oh and kyuuei, it definitely weird how much your upbringing affects how you look at guns. In the UK the police sometimes carry in the airport but they're probably the one copper you would never approach for any reason unless you saw someone who might need shooting. A gun almost forms a three metre exclusion zone where no one wants to be.
