It's something else, the mentality of people perhaps? I have no clue actually, Americans are probably a little bit too gun crazy but assuming the same would happen in Europe when you allowed guns is wrong in my opinion.
Well, three of the examples you quoted have more guns than the UK and less than the US, and have more gun deaths than the UK and less than the US, so I'm not sure what your point is there. Jamaica and many other countries with higher gun death rate than the US (e.g. Somalia) are outliers because the rule of law in general is weak, the police are corrupt, and border controls are poor, making it very difficult to control gun ownership. It is not only a matter of outlawing them, but being able to properly enforce that law. As you've kindly demonstrated, the correlation between gun density and gun deaths still holds.
Suicide is a non-argument anyway, I don't need a gun to kill myself, a rope is just as effective. And those homicides, I can take a knife or a hammer and kill someone too. I won't ever do those things though, not with or without a gun.
It certainly isn't a non-argument - a gun is by any measure the easiest and fastest way of killing yourself. In the time it takes to buy a rope, tie a noose, find a chair etc., many people will have second thoughts. The same argument applies to homicide - it is difficult and risky, not to mention visceral, bloody and horrifyingly intimate, to kill some-one with a knife or a hammer, whereas a gun can be used at a relative distance with ease and detachment.
Certainly if you are utterly, mercilessly determined to kill yourself or some-one else then you will be able to, but that doesn't apply in most cases, and guns make it easy to go through with it. The presence of guns also has the ability to turn any angry or violent confrontation into a murder scene in the heat of the moment.
Do you have any response to the fact that you are more likely to be killed if you have a gun in your home, not less? Self-defence?
Surprisingly enough , some of us feel safer enough without guns to protect them from criminals, and not willing to risk to get shot by your neighbor having too many beers at his barbeque party.
This.
Well spoken!!
I Feel safer for sure without guns, in my country you know you dont have to fear anyone can bring a gun to even normal people. I just dont like the idea that anybody can have a gun.
Ofcourse people can bring other weapons like hammer/baseballbat/knife but you can defend alot better vs that.
And with a gun, 1 bullet is all it takes you only have to pull the trigger.
this way you will get community of
