Something has changed
In the 1950s and early 1960s, when America was still a free country, guns of every description, including a sled-mounted 20mm anti-tank rifle, were available by mail.
All of the big department stores, like Sears, Montgomery Ward and J.C. Penney, had gun departments. And, gun sales were cash and carry; there were no FBI background checks.
Despite the easy availability of guns back in the day, there were no school shootings, workplace shootings or shopping mall shootings. Such things were unthinkable.
The Swiss have a citizen-soldier philosophy. True, fully automatic assault rifles are kept in Swiss homes as part of the nation’s military readiness. Again, there aren’t any mass shootings in Switzerland.
Obviously, some dynamic, besides firearms, accounts for these mass murders in the U.S. What is that dynamic?
Finally, I’d remind the Marxist-left anti-gun lobby that their proposed gun bans might, in fact, be unconstitutional. Remember that pesky Second Amendment? What part of “the right of the people to keep and bear arms shall not be infringed” don’t you understand?
