What does that have to do with anything? Explain please.

They can be. But that doesn't make it less true that there is a chance of it happening.

I disagree; I do not think that it would be better to ban guns. I have not seen evidence compelling enough to convince me that it is better to ban them, because I don't see massive spikes in crime where guns are allowed. And to me, it makes sense that I don't see that, because the vast majority of people who buy a gun are not doing it to kill someone. They do it for protection, or for sport (shooting ranges/hunting).

I'm a conservative, but - and maybe it's because I'm from the UK - I want increased gun presense in the police force, but absolutely no guns allowed in the regular civilian population.

It's not about reducing crime, it's about reducing death from crime or death from people trying to prevent crime (or who think they're trying to prevent crime, a la Treyvon Martin). If you get hit over the head with a baseball bat in a mugging, that's a tragedy, but you're much less likely to die than if someone shoots you in the head. And if you have to mace or tase or otherwise disable someone who is attacking you, at least you haven't killed them.

If no civilians have guns, then nobody gets shot.

If someone breaks into your house with a gun, and you also have a gun, odds are somebody's gonna get shot.

Yes, if guns are illegal for all civilians, criminals are still gonna have guns. But would you really want to shoot somebody with the intent of hurting them, even if it is in self-defense? Those are some pretty heavy words, to say that you've shot someone with the intent of hurting them. Self defense or not, you still shot someone.

Lets say we live in a world where no civilians have guns, not even criminals. Someone breaks into your house, and he (or she) has a knife. I think a metal baseball bat would be a better means of defending myself than a knife.
Knives might look more dangerous (and they might be more dangerous depending on the size), but the blunt force of a bat is more dangerous the way I see it.. A hard swing at the right location on the head could kill a person, if not make them unconscious. It's not as easy to knock someone out with a knife.

Also, all those people saying how they'd take their own guns to the cinema in case a gun attack occurs: have you even read what you're typing? Why should anyone live their lives in such fear that there's a good chance that one of the people you'll meet will be carrying a gun? I couldn't imagine having to take a gun to the freaking cinema - that's not where they belong at all

I have a baton in my room in case of emergency, and I'm very happy with that, because I know that the chances are that anyone breaking into my house will have a knife, unless they have some serious connections in the criminal world, which most burglers do not.

Couldn't give a shit.
