Helmke did not know what the hell to do. That was funny, great job, Colbert! The stuff-shirt, should have went along with Colbert, and then he would not have looked like such an ass.
Yes Colbert, made him look like an idiot, but don't let that fool you; I'm pretty sure Colbert isn't pro-gun either...I know he was just trying to prove a point, along with making Helmke look like a half-wit, but his last little rant didn't sound too pro-gun to me.
I could be wrong, but it looks like Colbert got a Helmke "look-alike" for the shots of his own face and spliced in his own comments with bits of an interview Helmke did with someone else.
Slightly funny, but no, I don't think Colbert has the slightest interest in the RKBA.
