Should he be carrying? Who knows? How serious is he? Plenty of "tough guys" who are nothing more than noise.
Lying politicians affect how many lives with their lies? Do we hang them? Lying insurance companies have killed how many? Do we burn them at the stake?

Just an idea.....(1)

Polygraph before purchase if armament is purchased from a dealer? Questions would need to be from a form created by someone with an ability to determine the likelihood of the purchaser to initiate a weapon encounter. Simple scoring system, cost to be added to purchase price.

Of course none of the above applies to gun deals outside of the loop.

(2) get guns back from nuts? No way to do it....period. If there are guns available, nuts will have some. If there are no guns available, nuts will build them. Precisely why chasing guns as the problem is ridiculous. Creating a defenseless populace should be criminal in itself.

I'm over my limit in wordiness....something I don't like much....but thought I would try to provide a little something constructive.

Good Luck......now your turn......you asked, now you provide what you think.
