Some important stuff is left out until the very end:
===
"We have guns at home, but they are kept for peaceful purposes," Martin Killias, a professor of criminology at Zurich University, told the BBC in 2013. "There is no point taking the gun out of your home in Switzerland because it is illegal to carry a gun in the street."
That's mostly true. Hunters and sports shooters are allowed to transport their guns only from their home to the firing range — they can't just stop off for coffee with their rifle.
And guns cannot be loaded during transport to prevent them from accidentally firing in a place like Starbucks
===
I've also read that even though the Swiss are permitted to keep guns at home, the government severely restricts the sale and ownership of AMMUNITION for such weapons.
I could be wrong about that.
In other words, to try to draw a comparison between the Swiss and Americans, insofar as the Second Amendment is concerned, is basically meaningless. Apples v. oranges.
