I agree with this article, for the most part:
The roots of mass murder
The irony is that over the last 30 years, the U.S. homicide rate has declined by 50 percent. Gun murders as well. We’re living not through an epidemic of gun violence but through a historic decline.
And:
But there’s a cost. Gun control impinges upon the Second Amendment; involuntary commitment impinges upon the liberty clause of the Fifth Amendment; curbing “entertainment” violence impinges upon First Amendment free speech.
That’s a lot of impingement, a lot of amendments. But there’s no free lunch. Increasing public safety almost always means restricting liberties.
We made that trade after 9/11. We make it every time the Transportation Security Administration invades your body at an airport. How much are we prepared to trade away after Newtown?
