This short piece by Amitai Etzioni  captures the difference between economists and non-economists. He says that rather than wait for gun control laws, we should just ban them in our own homes and post signs outside announcing that our homes are gun-free thereby becoming “ambassadors for gun control.”
I am reminded of the Hillaire Belloc poem:
Pale Ebenezer thought it wrong to fight.
But Roaring Bill who killed him thought it right.
