The Media Research Center did the math and found that since the release of the videos exposing Planned Parenthood’s baby-parts trafficking, of the 243 hours of airtime available to NBC, CBS, and ABC on their various news shows, only 73 seconds has been devoted to broadcasting the actual videos.

Statistically that is 0.008%, or a big fat zero.

Of that 1 minute and 13 seconds: Controversial video played: 0 seconds Controversial imagery shown: 0 seconds Controversial comments said: 1 minute, 5 seconds The news shows not once played even blurred or pixilated footage of babies’ hands and legs picked apart in a dish – footage prominently shown in the fifth video.

As the MRC points out, the networks do not have an ethical problem with undercover video. When the target of the video benefits Democrats or certain narratives, these surreptitiously recorded moments get all kinds of network airtime:

In September 2012, the networks spent 88 minutes in 3 days covering the Mitt Romney “47 percent” undercover video. ABC found the story worth 21 minutes, 19 seconds, CBS covered it in 31 minutes, 24 seconds and NBC spent 35 minutes, 40 seconds. … The nets rushed to highlight NBA owner Donald Sterling’s racist remarks. In 3 ½ days, the networks devoted 146 minutes, or more than 2 hours, to the story of secret audiotapes capturing his racism. In general, the networks are big fans of playing video. On January 7, ABC’s World News Tonight spent 114 seconds on zookeepers trying to get any mother gorilla to accept baby gorilla. During the Jeff Rossen reports, elaborate set-ups where Rossen stages situations to see how people react, Today spent 306 seconds on an unruly child August 10th and 299 seconds on a person confessing to use a fake resume on August 12.

This is a full-fledged coordinated cover-up designed to protect a left-wing institution.
