On celebrity, the NSA, and the hypocrisy of DOJ perjury prosecutions

Not a Texas-specific issue, but this has been bugging me: Can anyone justify why the US Justice Department (unsuccessfully) tried to prosecute "Rocket" Roger Clemens for perjury but somehow James Clapper, the director of national intelligence, not only hasn't been indicted for blatantly lying to Congress about the NSA phone spying program, the Obama Administration and senior US senators are publicly praising him?

At the time, Grits expressed dismay bordering on disgust that the DOJ would waste resources prosecuting athletes like Roger Clemens and Marion Jones over allegedly lying about steroid use while turning a blind eye to far more serious crimes. But that sordid spectacle appears even more embarrassing when compared to what's happening with Mr. Clapper. The basis of the Roger Clemens prosecution was the uncorroborated word of a shady informant and the government couldn't prove the charges in court. Clapper's perjury before Congress was both blatant and (thanks to revelations by Edward Snowden) entirely demonstrable.

The USDOJ's approach to those accused of lying to Congress smacks of shameless hypocrisy. They'll go after a celebrity for alleged perjury over trivia, then the Administration praises this mendacious NSA official for far more blatant, provable lies to Congress regarding much more serious subjects. My prediction is Mr. Clapper won't ever be prosecuted because he's in a position to reveal many more illicit activities about which the executive branch has probably also been lying.

Grits doesn't care if you're a Democrat or Republican, black, white, brown or green. This sort of calculated sophistry has denuded the Obama Administration of any remaining shred of credibility when it comes to defending, or even discussing, the Bill of Rights. And DOJ's failure to consistently pursue perjury prosecutions, declining to act when an Administration official lies but going after celebrities in a high-profile fashion, speaks to a smarmy unctuousness that's incredibly disingenuous. Just sickening.
