Glenn Beck can't keep his conspiracies straight.

It took the conservative host less than 90 seconds during his May 1 television show to produce one of the most glaring media contradictions in the wake of the Boston Marathon bombing. Not surprisingly, Beck didn't seem to notice the obvious inconsistency. That's what happens when you chase hollow and reckless conspiracy theories for a living.

The mix-up occurred during one of Beck's signature, rambling monologues about what really happened in Boston and who's really to blame. (Hint: Saudi Arabia.) But Beck managed to tie together two competing conspiracy theories that draw opposite conclusions about the Saudi government's involvement.

Recall that after the April 15 attack, Beck engaged in a wild conspiracy, insisting that a Saudi national student who had been injured in the blast and who was questioned by authorities was “absolutely involved” in the Patriot's Day attack.  (Law enforcement officials have repeatedly claimed he was not.) Beck called the student a "dirt bag," a "bad, bad, bad man," and  "possibly the ringleader" of the bombing that killed three people and injured more than one hundred.

The White House was “trying to make this a lone wolf crime so the Saudi government will be spared embarrassment, and the U.S. will be spared explaining how a terror cell was active when we have Al-Qaeda on the run,” Beck told radio listeners on April 18.

“You want to know why we have terror over and over in our streets?” he asked on April 22. “Saudi Arabia. It is time someone on network television says it.” The host even called for President Obama to be impeached for what the host considered to be a sprawling government cover-up surrounding the student, Saudi Arabia and Al Qaeda.

On May 1, Beck returned to the claim insisting, “We know Saudi Arabia is involved.”  

Then, less than 90 seconds after implicating Saudi Arabia, Beck latched onto yesterday's conspiracy-of-the-day claim, courtesy of Britain's Daily Mail. It reported Saudi officials had delivered a “very specific” written warning to the Department of Homeland Security in 2012 about Boston bomber Tamerlan Tsarnaev. Saudi officials were allegedly so concerned about Tsarnaev's radical ties that his visa request to visit Saudi Arabia had been denied. Beck's site, The Blaze, also pushed the story, as did scores right-wing blogs.

The Department of Homeland Security, the White House, and Saudi Arabia's U.S. Ambassador have all since categorically denied the Daily Mail's claim. The newspaper has produced no evidence to back up its anonymous source's dubious allegation.

That didn't matter to Beck. Because the unproven claim made the Obama administration look bad, and because it made it look like government officials had missed obvious warning signs about Tsarnaev, Beck embraced the Saudi story as truth. But that left him in the very awkward position of insisting Saudi Arabia was “involved” in the bombing (and not in a good way), while simultaneously reporting Saudi Arabia tried to warn the U.S. about the bomber.

In Beck's telling, Saudi Arabia officials were both the good guys and the bad guys in Boston. Only he would try to paper over a boulder-sized inconsistency like that in the span of 90 seconds.

Question: Was it keen programming like this that convinced executives at Cablevision to add Beck's Internet channel to Cablevision's New York City metropolitan cable system?
