This act is getting tired.

In recent years, conservative activists, under the guise of renegade journalism, have been churning out undercover “sting” videos supposedly capturing reprehensible behavior by their mostly liberal targets. Those targets have included low-level workers at ACORN, a fundraiser at National Public Radio, and now officials at Planned Parenthood, among others.

The activists release a series of videos in an effort to build a big takedown story, and the press usually plays along. Meanwhile, activists coordinate with right-wing media players and members of Congress to generate simultaneous outrage over the clips.

The problem for the activists, and the problem for journalists who excitedly treat the clips as news, is that the videos invariably turn out to be doctored, filled with deceptive edits, and missing context in an effort to manufacture scandal.

The whole cycle has become a media cliché, but it's one that conservative partisans cheer. And they're cheering again this month as the Center for Medical Progress releases edited clips to claim Planned Parenthood officials have been caught discussing how the organization “sells the body parts of aborted fetuses” and “haggling” over prices for “baby parts.”

Both incendiary videos have been proven to omit crucial context undermining their central claims.

While some outlets have done a good job calling out the deceptive nature of the campaign against Planned Parenthood, too many veer into a he said, she said construction while writing up the allegations. (See the front page of yesterday's New York Times, for example.)

Commentary's John Podhoretz was impressed by the roll-out:

This Planned Parenthood video drip-drip-drip is the first time anyone has properly followed the Andrew Breitbart playbook since his death. -- John Podhoretz (@jpodhoretz) July 21, 2015

Podhoretz was likely referring to the ACORN sting videos that Andrew Breitbart's site helped roll out in 2009, as the conservative media waged war on a nonprofit group that helped poor people -- a war waged via dishonest undercover clips that captured James O'Keefe and his sidekick, Hannah Giles, famously getting advice from ACORN workers in various field offices on how prostitutes could skirt tax laws. The ACORN videos that the press went bonkers for were built around the fundamental lie that O'Keefe entered the ACORN offices dressed like a cartoonish pimp and workers still counseled him. They were also bolstered by deceptive editing.

California Attorney General Edmund G. Brown, Jr. pointed out that the videotapes were “severely edited by O'Keefe.” According to a 2010 New York Daily News article about an investigation into O'Keefe's sting at a Brooklyn office, “a law enforcement source” said the conservative activists had “edited the tape to meet their agenda.”

Three separate investigations also cleared ACORN workers of any criminal wrongdoing. But the damage was already done -- the organization folded in 2010 amid the controversy.

In 2011, O'Keefe released a set of sting videos to expose NPR's supposed liberal bias. It featured fundraiser Ron Schiller having lunch with two potential (albeit fake) Muslim donors and Schiller making disparaging comments about Republicans and Tea Party members. It was soon revealed that the tapes had been highly edited and done so in a way to make the Schiller comments seem more damning than originally believed. (In the short term, the videos worked -- NPR's CEO was forced to resign.)

The anti-choice group Live Action rolled out a series of undercover videos in 2013 claiming to catch Planned Parenthood conducting “illegal and inhuman practices.” Like the others, the Live Action videos were dishonestly edited to improve the story activists wanted to tell.

Let's put it this way, when conservative activists release an undercover sting video that doesn't rely on dishonest editing to manufacture its point, it will be their first.

But the dismaying part is the formula works in the short term because too much of the media, drawn to the heat and the light of agitated conservative outrage, almost immediately types up the tapes as news despite the fact that for six years running, the established record shows that these types of tapes are regularly debunked. (Joining some other outlets that have called out the spin, a New York Times editorial this week cut through the ambiguities and declared the clips to be part of a larger, deeply dishonest smear campaign.)

Does the press honestly believe these tape releases aren't carefully choreographed by conservatives? Meaning, the press seems to treat as news that the tapes generate outrage within the conservative media and the Republican Party.

From the New York Times last week: “The video spread rapidly over social media and was discussed on talk radio.”

But there are clear indications that the outrage was planned in advance, so why is the ire considered newsworthy?

In fact, we now know at least two key Republican congressmen who expressed outrage at Planned Parenthood last week were shown the first sting video weeks earlier -- and did nothing with the information. Apparently not wanting to step on the media roll-out, Rep. Tim Murphy (R-PA) -- a member of the House Pro-Life Caucus and chairman of the Energy and Commerce subcommittee -- and Rep. Trent Franks (R-AZ) both sat on the information contained in the video and only sprang into action after it was released to the press.

After the right-wing's NPR video was proven to be misleading in 2011, some reporters conceded that activists releasing bogus clips have the advantage because the press doesn't want to slow down and ask questions about whether the clips are dishonest or not.
