I'll disagree slightly that guns are weapons. Firearms can be weapons, as your definition pointed out, it's the use which makes an object a weapon. A spoon can most certainly be a weapon, as can any other household object!
Pedantic aside, I have never said I disagree with firearm regulation, I gave my views on it earlier that in America I think gun registration should be compulsory, a licence is required for ownership and that licence is dependent upon doctors reports, police background checks etc (similar to what we have in the UK) and these are reviewed at regular intervals.
It is frustrating when people who don't understand what they are talking about decide to implement restrictions. Remember the 'barrel shroud' ban? I saw a news report of this person who'd got them banned in the states, she couldn't even explain what one was yet campaigned to have it banned. (here it is!)

Oh, i don't disagree that website was biased, but the stories about self defence were genuine enough which was the only point i was making - how would those people have faired without a firearm.
I can't comment on what has been found in that journal as I haven't read it. It would be interesting to see it's findings though.
The UN documentation - 60% of all homicides... that's taken from countries all over the world including places almost lawless like certain places in south africa, places in south america etc. It even states the lowest is 19%, highest 77%. So I don't see what exactly your point is? That lawless places with no gun control have a high murder rate with firearms...?
In the UK figures are somewhere around 3,000 people killed a year by knives, approximately 50 by guns. My point was that the tool to commit the crime might change, but the crime will still be committed. It's the person, not the tool that is the problem.
Your last point about the highest rate of gun related injuries - but what context? Were those injuries from home defence, accidental wounding, trapping your finger in part of the gun mechanism, shooting at a range and recoil spraining your wrist...?
But yes I agree, regulation is needed and it needs to be done by experts in firearms, not slimy politicians looking to score points with voters by throwing around slogans and marching on some crusade in the name of children when really it's just to advance their own political and financial agenda. (see vid above!)
