This news probably doesn't make the Brits very happy. The Guardian is reporting that the United States has released one of the men who helped train the 7/7 bombers:

The unreported sentencing of Mohammed Junaid Babar to "time served" because of what a New York judge described as "exceptional co-operation" that began even before his arrest has raised questions over whether Babar was a US informer at the time he was helping to train the ringleader of the 7 July tube and bus bombings.

Lawyers representing the families of victims and survivors of the attacks have compared the lenient treatment of Babar to the controversial release of the Lockerbie bomber, Abdelbaset al-Megrahi.

Babar was imprisoned in 2004 - although final sentencing was deferred - after pleading guilty in a New York court to five counts of terrorism. He set up the training camp in Pakistan where Mohammad Sidique Khan and several other British terrorists learned about bomb-making and how to use combat weapons.

Babar admitted to being a dangerous terrorist who consorted with some of the highest-ranking members of al-Qaida, providing senior members with money and equipment, running weapons, and planning two attempts to assassinate the former president of Pakistan, General Pervez Musharraf.

Yes, the intelligence business is a dirty game. You don't get Dudley Dorights to infiltrate al-Qaeda and other terrorist outfits. And it is unlikely this fellow experienced a conversion and has sworn off jihad.

But revelations about his cooperation makes him a marked man in terrorist circles. Releasing him may be akin to a death sentence if he tries to join up with another terrorist group. Chances are, Babar will either set up his own terrorist network or "retire" from the game. Either way, we know who he is and will be keeping an eye on him in the future.
