Awhile back I took an interest in those "kid gets ahold of a gun and shoots someone" stories, and started digging up a lot of additional information on them.

In nearly every single case, it turned out that the parents were criminal dirtbags.

Not that this makes such incidents any less tragic; it doesn't, but the media likes to spin these incidents in such a way as to portray them as a common thing that happens to regular Joe Citizen the Gun Owner, and it's simply not true.
