Was Pittsburgh shooter was yet another right-wing domestic terrorist.

AKA the GOP lost four voters this morning....

He feared an Obama gun grab? Gee, I wonder where he could have heard that.

Indeed, a story replete with NRA-style fearmongering about the looming "grab" -- which has been fueling a run on guns at local shops -- ran just three days ago in the Pittsburgh Tribune.

We've been reporting for awhile on the surge in gun sales, and how the paranoia around guns is making the more unstable elements of the right particularly edgy. Inevitably, that edginess is going to break out into actual violence -- as it appears to have done today.

Ironically, this is exactly the kind of incident that law-enforcement intelligence-gathering is supposed to help prevent -- intelligence like the Missouri State Patrol report so hysterically attacked by these same paranoid right-wingers. I tried to explain at the time that these kinds of extremists are in fact a very real danger to people in law enforcement, but all anyone on the right wanted to talk about was Ron Paul bumper stickers. Well, there you go.
