Wretchard is unusually good today at common sense:
“We focus on things because it is prohibited to focus on people. The TSA looks for things — scissors, liquids, shoes, etc — but it doesn’t stop the underwear bomber. People now want to blame ‘access to guns’ for the Tsarnaevs. But it would be uncouth to ask after what they heard from their imam or their teachers.”
Indeed, and I agree with his conclusion: I won’t hold my breath waiting for our PC strait-jacket to be loosened.
THE TEXAS SCRIBBLER 
Tsarnaevs? Criminal (or terrorist) cadre will always be able to get guns and ammo, no matter what kind of restrictions are put on sales.
Straight off the old bumper sticker: “When guns are outlawed, only outlaws will have guns.” And politicians, of course.
I would like to know where these Boston jihadis got their explosives and electrical detonators. And how many more disaffected Chechens are planning to use more. Could be homemade with blueprints off the ‘Net but only in the unlikely event that the self-involved perps are willing to risk their own lives by following the directions.
