Lets clearly define what is considered a child. Jon Stewart has been using a stat that includes 19y.o. gang bangers to try and shame gun advocates lately. People can rig the stats any way they want to push their agenda....I mean, I get the point, but think it'd be interesting to see if there's any statistics on how many times a firearm is used to protect a child versus how many die from them.
Keeping a child safe, in my opinion, should also very very much include proper storage and discipline for instance on the part of the adult.
