We don't know how it happened exactly.<quoted text>
While I don't want to pile on the guy, he needs to lose his concealed weapon license as well as his guns. And he probably shouldn't be a firearms instructor either.
The article is very apologetic, and police seem very supportive of this guy, almost to a fault.
People should not allow autistic 8 year-old to get their hands on a loaded firearm. "Oh well it was an accident" does not absolve this guy of his negligence.
so many possibilities of how this happened, it may not be the owners fault.
