Abu Ghraib a crime against humanity? Yes, that's similar to ethnic cleansing in the Balkans. That's nearly exactly the same thing as the genocide in Rwawanda. That's definitely on the same level as Pol Pot.
The difference however is Abu Ghraib didn't put intelligence sources at risk, it didn't endanger the lives of people. How many people died in Abu Ghraib from being photographed with underwear on their head? How many innocent lives were put at risk because of Abu Ghraib? I am certainly not defending the soldiers involved in that situation but to try and draw some moral relativism between the two cases is absurd. You likely have no idea how Americans are treated by the Taliban and Al Q when they're captured.
Ask Daniel Pearl: http://en.wikipedia.org/wiki/Daniel_Pearl
By the way, the guys in Abu were fighting on the same side as the guys that beheaded Daniel Pearl. They were combatants. They weren't innocent little girls walking to school. The irony is if the US soldiers at Abu had shot those prisoners on the battlefield, nobody would have complained, but they put underwear on their heads and the world freaks the hell out, yet quietly forgetting about cases like Daniel Pearl. We could argue Geneva convention all day long, but until the Taliban is a signatory to that convention or wears uniforms declaring themselves as part of a legitimate military force, the Geneva Conventions never applied, though of course we (meaning the US military) still follow those rules. And those that didn't -- were punished.
While we're so busy being outraged, let's get outraged about the Taliban stoning women to death. http://www.bbc.co.uk/news/world-asia-15688354 Bradley Manning helped the Taliban find informants. http://thelede.blogs.nytimes.com/2010/07/30/taliban-study-wi...
One specific and direct result of Manning is the case of Shakil Afridi, the doctor in Pakistan that helped find Bin Laden. He's in a Pakistan prison for 30 years after ostensibly being tortured.

Since Mr. Manning directly made his discovery possible, what punishment should Manning receive? There are dozens and dozens of intelligence sources and relationships that were significantly harmed because of Manning.
If you have ever spent any time with a security clearance, you'd know that there are countless unintended consequences that result from revealing a source or a collection method. Being morally outraged over Bradley Manning puts you in the same shoes as a Taliban sympathizer because not only was Manning a soldier, sworn to uphold the Constitution, the lives of his fellow soldiers, allies and others were in his hands. He was given a position of public trust and the responsibility that goes with it. Yet because he had emotional and personal problems he chose to do what he did.

A raw information dump isn't "blowing the whistle," it's an intent to inflict harm on the United States and allies. If you wanted to expose a security hole in Gmail, for example, you wouldn't expose every single gmail user's information. You'd expose the amount necessary to reveal the problem. The simple truth is that Manning is a kid, he's intelligent to some degree, but he certainly isn't an Edward Snowden. Manning had no idea what he was doing. By his own words he said he didn't intend to harm the United States. Either he's a liar or a complete fool.
There are countless intelligence and diplomatic relationships that have been harmed, in addition to people who have been directly killed, captured or targeted as a result of Manning.
Snowden on the other hand, released information about illegal activities against US citizens that were in direct violation of the law. The Snowden releases, while potentially compromising national security from a strategic standpoint, didn't put any lives at direct risk. Manning's releases however put dozens of people directly in the line of fire. I am not going to defend Snowden, however a better case could be made for him than Manning and certainly no comparison could be made to Abu Ghraib. That's just tomfoolery.
