First to know - Last to care!
I neither said a word about mandating firearm training nor denying Second Amendment rights.So are you are asserting that only those with proper training are allowed to discharge a firearm to defend themselves?
In no way am I against proper training in the safe handling of guns, but that isn't a requirement of owning, bearing or using a firearm since it's a right protected by the 2nd Amendment.
And last I checked, the only relevant matter is whether they used the firearms in a legal manner. Even if they had shot someone that was threatening them. That should be the only relevant factor.
