“Heavily edited.” That’s been the go-to excuse of corrupt progressives who’ve been caught on video, all the way from James O’Keefe’s ACORN sting operation to undercover footage of Planned Parenthood negotiating the price of body parts harvested from aborted fetuses.

The Planned Parenthood videos, for example, were so “heavily edited” that the organization commissioned a firm to perform a frame-by-frame forensic analysis to uncover those flagrantly obvious cuts.

So it’s no surprise to learn that EPIX, the cable network airing Katie Couric’s documentary, “Under the Gun,” isn’t concerned about the discovery of manipulated audio. Just watch it and decide for yourself how you feel.

“Truth is the ultimate weapon.” Cute.

But … it’s a polarizing issue, and EPIX is simply trying to start a dialogue — if necessary, by airing deceptively edited dialogue.

Stephen Gutowski reports in the Washington Free Beacon:

Couric can be heard in the interview asking activists from the [Virginia Citizens Defense League], “If there are no background checks for gun purchasers, how do you prevent felons or terrorists from purchasing a gun?”

The documentary then shows the activists sitting silently for nine awkward seconds, unable to provide an answer. It then cuts to the next scene.

However, raw audio of the interview between Katie Couric and the activists provided to the Washington Free Beacon shows the scene was deceptively edited. Instead of silence, Couric’s question is met immediately with answers from the activists.

Michael Moore used a similar technique with the late Charleton Heston in his critically acclaimed “Bowling for Columbine.” Couric, of course, was a long-time employee of NBC, the network that famously rigged a pickup with an incendiary device in its report on exploding gas tanks, so she’s learned from the best. But now her gun documentary is blowing up in her face.

But wait … the director can explain.

Here’s the video clip so you can decide for yourself if Couric was just doing viewers a favor by providing some space to think.
