Since that awful Sunday in Sanford, Florida, back in February, the media have shown time and time again they don't understand how the American justice system works.

Take ABC legal analyst Dan Abrams who on Thursday's Nightline said, "So even if Zimmerman was on his back, even if he was losing a fight, he still has a lot of explaining to do and is going to have to prove that Trayvon Martin was the initial aggressor" (video follows with transcript and commentary):

ABC broadcasted two completely one-sided reports on Thursday's World News and Nightline on the supposed "huge spike in the number of Americans operating in the shadows, trying to take down the U.S. government even with violence," as anchor Diane Sawyer put it. Correspondent Dan Harris's main external source for his reports was a media favorite, the left-wing Southern Poverty Law Center [audio clips available here].

As she introduced Harris's first report on World News, Sawyer trumped that "a new study finds there are now nearly 1,300 militias and other extremist groups in this country, an increase from 149 groups in 2008. And one of the fastest-growing groups is called 'sovereign citizens.'" However, an examination of the SPLC's report in question find that many of these supposed "extremist" groups have been around for longer than four years, and the only change is that the leftist organization recently designated them as such.

The journalists on ABC often sound like they are plagiarizing Barack Obama's talking points. On Tuesday night, this was literally true. During live coverage after the State of the Union, George Stephanopoulos informed, "...Vice President Biden just before the speech gave a call to Democrats. And he summed up the speech with this phrase, Bin Laden is dead, General Motors is alive." [See video of the two clips below. MP3 audio here.]

On the same day's Nightline, with no explanation that he was stealing Biden's line, co-anchor Terry Moran parroted, "Osama bin Laden is dead. General Motors is alive. Those points folded neatly into another of the President's goals, to wrap himself in the American flag." Good thing the Democrats, Stephanopoulos and Moran are all coordinating.

ABC trotted out the "best of" Newt Gingrich slams on Thursday, finally revealing the results of an exhaustive Brian Ross interview with Marianne Gingrich, the former Speaker's ex-wife. Ross boasted that his scoop could be seen as a "January surprise" to harm Gingrich. Recycling old attacks, Ross eagerly prompted the ex-Mrs. Gingrich: "You know his secrets. You know his skeletons." [UPDATED: See video below. MP3 audio here.]

How bereft of new information was the segment? According to reports that broke on Wednesday, Ross sat down with Marianne Gingrich for two hours. In the eight minute segment, ABC only used two and a half minutes of actual footage from that interview. But Ross breathlessly hyped, "And we begin tonight with a story at the white-hot intersection of presidential politics, private lives and character."

Nightline co-anchor Terry Moran delivered a surprisingly positive assessment of Tim Tebow on Monday night, lauding the Christian quarterback as "inspired," "lifted up" and "strengthened" by "a power beyond his understanding."

Moran also highlighted, "Psychologists are increasingly finding that the very fact that a person has religious faith can help lead to the kind of success Tim Tebow has had." It wasn't all complimentary, however, the program's journalists repeatedly went out of their way to assert just how "controversial" Tebow is.
