In my opinion a key societal objective is to keep people safe...the linked article shows overwhelmingly that countries having significant gun restrictions have an order of magnitude fewer gun related deaths...you'd be hard pressed to argue that there's no correlation here.
BTW, I know a little bit about guns...while I don't own one, as a teenage I ran a rifle range at a Boy Scouts summer camp...was responsible for ensuring all the younger scouts knew how to handle the gun, clean it and, of course shoot accurately. Later, I shot a military sidearm, BAR and even manned a 5"-38, but that doesn't count...or does it? As Justice Scalia said..."The Second Amendment is NOT unlimited (my emphasis)"...you can't own a piece of artillery and the government has every right to restrict other weapons as well (e.g. AR-15s).
When I hear arguments that say "Law Abiding" citizens should be able to purchase AR-15's, or 'Open Carry' whenever and wherever they choose, I think of the retired Police Captain in your fair state who got upset with a cell phone user in a movie theater (who was checking on the babysitter)...told him to shut it off.. escalation ensures and the cellphoner tosses pop corn at him...so what does this esteemed "law abiding" Police Captain do?...he pulls out his pistol and shoots the "Bad Guy" dead in front of his wife.
And what do we "get" from owning those AR-15s that tips the balance of safety and sanity in that direction?...Anthony Bourdain, in one of his last episodes before his suicide, visited a group of folks in Pennsylvania, I believe, who wanted to show how they used their hard-won access to fully automatic assault rifles (can be done with much oversight)...so after all that 'good citizen' effort, their pride and joy was blowing up some watermelons! So in their minds, it's a fair trade to be able to laugh and giggle at exploding fruit, while children literally have their heads blown open by a similar weapon operated by a here-to-fore unknown non-law-abiding citizen.
Am I making myself clear?
Allowing access to weapons - especially those designed for military use - applies to all citizens...even those who harbor evil intent, but haven't yet run afoul of the law...there's no way of knowing ahead of time, short of subjecting everyone over the age of reason to annual mental evaluations. Arming more and more citizens who carry those weapons outside their homes only increases the chances for lethal outcomes when people get frustrated and angry (i.e. lots and lots of opportunities)...
I'll be happy to provide more evidence as to why ownership of assault rifles or "open carry" is frivolous and juvenile...I suspect that more than a few law enforcement institutions would agree...just imagine responding to an "Active Shooter" emergency, when EVERYONE has a weapon and wants to be the 'Hero'...no thanks.
Your turn...
