OK, so now I get it. If you know someone has a felony conviction or a history of mental illness, you can no longer invite them into your home if you have a weapon. While there are aspects of this case that seem to support the decision, I feel the ruling is far too broad. The NRA needs to look into this as it opens the door for further entrapment of honest gun owners.
I see no reason to believe that having the gun locked up wouldn’t have been sufficient to prevent this result.
We can’t know because the gun owner was an idiot who essentially let the felon take his gun and keep it under his own pillow.
