258. Intent matters.

I carry my gun for the explicit purpose of protecting human life. Period. And I have a decade-long track record of not fucking up.

Sometimes, with the right intent, firearms that are, as you say, 'designed to injure, damage or kill' can be used to preserve human life. (and human life is extremely precious to me)

That said:

Both issues extend in dimensions you didn't cover. The pool is not just a threat to a child that lives in the house. It's a potential threat to any kid exposed to/aware of its presence in any form. To any kid that might be passing through the yard it is sited in, lawfully/invited or otherwise. That helps your point.

But on the flipside you have to consider, again, not just kids that live in the household with the gun, but visitors, and secondary parties. Meaning, if someone breaks into the house and steals the gun, all the children exposed to that weapon downstream have to be considered. Then you have to consider victims within a reasonable physical distance of the gun, when in the hands of an incompetent or malicious user. 360 degrees of possibilities in 3 dimensions, for ranges up to a mile.

All of that said, there are a crapton of guns in this country that are, I accept as you stated, 'designed to kill, injure, or damage'. More than 300 million of them. That's an awful lot of devices 'intended' to kill, injure, or damage, that are not used to do so in greater frequency than innocuous, regulated, non-designed-to-kill, harm, damage, things that we use in our every day lives; like bathtubs.
