LAWRENCE O’DONNELL DEMONSTRATES HIS IGNORANCE ABOUT FIREARMS AND FIREARMS LAW, but his lack of knowledge doesn’t stand in the way of strong opinions! Video here.

Really, this kind of ignorance is inexcusable, at least among people who pretend that their opinions matter. It’s like commenting on sex education when you don’t know which bodily parts go where.

UPDATE: A commenter observes: “This sort of cluelessness would be laughed off the set of any sports panel show. Why do we tolerate it in our political discussion?”

You’d think the McLaughlin Group would set a higher standard.
