How do you know that someone with a concealed weapon wasn't at the theater where the shooting was at? Because a sign told them not to? Because you assume that someone with a gun would choose to kill a shooter instead of running themselves?
If you are carrying concealed with a permit, and you violate a location with such a sign? You WILL face criminal charges and lose your permission to ever Carry Concealed again. While the odds aren't great that someone would have had a carry conceal to begin with, that sign virtually guarantees that, unless a CC holder just forgot (which is uncommon. We tend to know we're carrying and either avoid places that ban it or simply lock it in the car), we don't carry in those places.
Nor is there any evidence that a CC would have changed the outcome. We can armchair QB the entire event, but reality is that no one will ever know.
There's a big difference between firing a gun when you expect it and hearing one fired when you don't. Suicide by cop may have been his intention, but the reality is, now that he is in jail, he obviously backed off that plan because he realized it wasn't what he really wanted.
No way anyone can answer those, so these little pissing contests accomplish nothing.
My recommendation is mental health professionals required to report potentially dangerous people so they cannot buy a firearm without clearance from said doctor, or two others who disagree with that professional assessment.
Simply leaving that doctor will not eliminate someone from being considered potentially dangerous.
ALL gun sales (Note the word SALES, not gifts within family.) must take place through a licensed FFL dealer, much like how internet sales of firearms have to operate.
I've heard from many 'what about just ordering a gun off the internet'?
Reality is, you can't. It is shipped to a licensed FFL dealer within the area who will run the background check prior to giving the weapon to the buyer, and only then if he/she passes said background check.
If they don't? They ship it back to the seller.
Private sales should be channeled the same way. Go to a licensed FFL, they facilitate the background check and transfer, filling the numbers in their state kept files. Feds have no need for that.
Harsher sentences, such as minimum sentences, for using a gun in a break in/burglary, such as twenty years prior to even beginning to become eligible for parole.
