James O'Keefe has a couple of NPR scalps on his belt, and good for him I guess. Jonah Goldberg tweets, "I remember when undercover stings are what made '60 Minutes' America's greatest journalistic enterprise," presumably hitting at hypocrite liberals who are irritated by O'Keefe's stings.
But O'Keefe's brand of journalism owes more to "Borat" than to "60 Minutes." In Borat, Sacha Baron Cohen's M.O. was to walk into situations and be the biggest, most annoying jerk he could. Sometimes people were irritated, in which case the comedy came from their consternation, or they remained polite—in which case the comedy came from them accommodating a huge jerk in their midst.
O'Keefe, I don't think, has ever unconvered real malfeasance at the organization he targets. Instead, he's mostly taken advantage of humankind's natural tendency to avoid confrontation or to be a little too solicitous. He's the kind of guy who'd videotape you listening to your grandfather's racist grumblings with a strained smile on your face, then release it to Fox News as an exposé of your own racism.
Most people aren't inclined to loudly confront wrongheaded people they've just met. As long as that impulse exists, James O'Keefe will have plenty more exposes he can release.
