I think 8 deaths in a knife attack is an outlier as 26 in a gun attack may be. I'm sceptical of the claim that last week's assailant would have killed more than 8 with a knife without somebody stopping him or the vast majority of the children being evacuated. Running away just works better against a knife unless completely cornered and even then some of a cornered group may escape. Evidence (http://news.bbc.co.uk/1/hi/uk/30883.stm) is that people will put themselves in the way to protect children in their care and with even a child's chair may be able to delay the attack for vital seconds. Against a gun even such a selfless act is unlikely to cause much delay.

Yes halving the number of deaths in each attack is a benefit but not one that necessarily overrides all other factors.

That's all reasonable. I think you have to consider that many of these knife attacks have wounded far more than 8, >20 just last week. If the person doing the wounding were using a knife more suited to the task, and was more competent at using it there could easily be a much higher death to wounded ratio. Now obviously this plays into the fact that a gun is easier to use, but it doesn't mean that it can't be done. If you can wound 20 with a knife, you can kill 20 with a knife. I suspect if they all ran when he came in to the room a few more would have been saved, shooting 20 running targets is non-trivial. The problem is they were probably all paralyzed with fear. I suspect hiding under a desk would be a more likely reaction, one that doesn't help at all.

>Against a gun even such a selfless act is unlikely to cause much delay.

Look at the attack on Rep. Giffords [1] "Loughner stopped to reload, but dropped the loaded magazine from his pocket to the sidewalk, from where bystander Patricia Maisch grabbed it. Another bystander clubbed the back of the assailant's head with a folding chair, injuring his elbow in the process, representing the 14th injury. The gunman was then tackled to the ground by 74-year-old retired US Army Colonel Bill Badger, who himself had been shot, and was further subdued by Maisch and bystanders Roger Sulzgeber and Joseph Zamudio. Zamudio was a CCW holder and had a weapon on his person, but arrived after the shooting had stopped and did not use the firearm to engage or threaten the gunman."

Gunmen get subdued all the time, but when it's a classroom of 5 year olds and you presumably start with the 1 adult teacher it becomes a lot harder.

>Yes halving the number of deaths in each attack is a benefit but not one that necessarily overrides all other factors.

I think this is key. I wouldn't consider it nearly enough of a benefit to outweigh the pros of gun ownership such as self defense, freedom, and liberty.
