You've got to admire American free enterprise:

Particularly like the potential use of the cushions as a bulletproof shield...
After quite a few visits to the US I have to admit that their saying "An armed society is a polite society" has some credence. Especially when driving, road rage is very rare and avoiding eye contact is de rigeur.
The right to bear arms is an article of faith to many Americans, going back to the Revolution, and they aren't going to be reasoned out of it. I suggested, tongue in cheek, on a US ethics discussion list that were they to arm teachers then maybe the logical next step could be to arm the children. The first vitriolic response cited an occasion when armed children acquitted themselves well in the War of Independence and that they would be happy to do the same today.
Great country, some puzzling people. They think the same of us.
