The Sandy Hook shooter took his Mother's guns from her safe after he killed her. When you are at the point that an individual will kill his Mother in order to visit mayhem on a school full of children, another law on gun storage isn't going to help.
Hardening the school would have a better chance than another layer of laws that will be used to harass legal gun owners rather than eliminating a sick perp.
That won't stop the left from trying to pass as many laws that do just that-it is never about ending the mayhem, it is about whittling the rights down a little bit at a time.
Nobody here seems to understand-this was all by design. It was totally predictable, and foisted on a willing minority that could be emotionally swayed by symbolism over substance.

Best,
