* Thomas Drake, an NSA employee who favored "ThinThread" instead of the later-adopted "Trailblazer" internet surveillance scheme, who then created a Hushmail account and fed classified documents to a reporter from it.
* Shamai Leibowitz, an FBI contractor/interpreter, who fed the contents of an cable intercepted from the Israeli embassy to a blogger because he felt it implicated Israel in an attack on Iran.
* Stephen Jin-Woo Kim, a career civil servant at State who worked on counterproliferation and North Korea and fed classified documents about North Korea to Fox News, and then lied to the FBI about having any contact with journalists.
* Bradley Manning
* Jeffrey Sterling, who was fired from the CIA, lodged a series of employment law disputes with the CIA, attempted to write a memoir about his time at CIA, and then fed classified details about Iranian counterproliferation to a reporter which put a human intelligence resource at risk.
* John Kiriakou, a CIA counterterrorism official who worked in Pakistan, who outed two covert operatives to a reporter (they had allegedly been involved in the Bush-era interrogation program).
Of this list, Kiriakou and Drake are sympathetic to me, but every single case here seems like a valid prosecution; when you take a role that requires you to handle the most sensitive data the government handles, you cannot share it with the press expecting not to end up arguing your side of the story in a court of law. You certainly can't out covert operatives, or feed foreign intercepts you translate to bloggers!

Is there anything that can reign them in? Or should I say convince them to reign themselves in. I don't think so.
Sorry for the rant.
Advice for press: Get trained in spycraft (throw away cell phones, false names, strong file and email encryption, Tor...). but most of all don't become too cozy with our leadership.
News has become a celebrity sport, and it's too late for "too cozy".

But to your point: it doesn't matter if Obama personally investigated the cases himself or if a witchhunt is led by a middle manager. He is the top executive, what he says or implies trickles down the chain of command. If he passed along the word that these prosecutions weren't worth the time and effort, then the immense work that goes behind building these cases would, quite likely, dissipate.
Read up on Mark Klein's whistleblower case. It wasn't just press surveillance - it was the origin of surveillance of everybody.
Keep in mind that under Obama, more alleged government leakers have been prosecuted than all of his predecessors combined:

This includes administrations that oversaw such problematic eras as the Cold War, the Vietnam War, the McCarthy Era, and of course, the War on Terrorism.
