Re: Guns in America
"I will say, however, that as an American there is one reason why many of us hate AR-15s. The reason is that in 2012, two weeks before Christmas, a mad man killed 20 children with one."
Whilst those events are unspeakably tragic, it's worth bearing in mind that Derrick Bird killed 12 people in Whitehaven using a bolt-action (albeit magazine-fed) hunting rifle.
In the right hands, it makes not a jot of difference whether a gun is Fully-Automatic, Semi-Automatic or Manually Fed.
China has had a spate of nasty knife attacks, with attackers killing 8+ children at a time with bladed weapons.
Much was made of the Washington Beltway Snipers using a Bushmaster (because it's black and scary looking), but for that job - with a modified car, etc - a bolt action would have been as, if not more effective.
The numbers surely are irrelevant. One innocent life lost is too many, and that means (once you have some sensible, basic regulations to make criminal access inconvenient) addressing the person, not the object.
