There are commenters saying we need to ban guns. I think he should be treated as if he were anyother person (the officer). If he was negligent, then he should be charged. I think it would be kinda hard to not be negligent in this case, but anythings possible.
I did find one comment kinda interesting. "I keep my guns empty, in a steel gun locker (cost $75) with the gun locks on. The gun locks which BTW are a mandatory part of the purchase of any weapon". Does anyone actually use the gun locks? I know they come with every gun and the sheriff departments give away free gun locks, but are they actually usefull? I keep my firearms in a large heavy steel safe (a lot more then $75 unfortunately) except for my home defense piece. However I have no kids so I don't have that worry.
