you cannot walk into a school with a pool and kill 20+ kids. You're comparing accidents (a unfortunate part of life) to an object which give a single individual power to take many lives... which is also "easily" available.

I'm not saying people shouldn't be able to have guns, but I don't think there's justification for assault rifles. There's a reason we make an effort to track and limit access to materials which can be used to make large explosives. The question is how much control over which of these potentially dangerous items should the law be allowed, given that it's virtually impossible to control it all.

You are severely underestimating my ability to use a pool as an instrument of death.
