The high court's decision to uphold the computer hacker Gary McKinnon's extradition to the US has provoked an outpouring of anger online.
The subject is one of the top 10 trending topics on Twitter under #freegary. It is also trending under #garymckinnon. Twitscoop shows a graph of how interest in the story shot up following the decision.
Many users have attached "Free Gary" logos to their Twitter avatars.
Peter Lamb, from Glasgow, sums up the mood. He writes: "It appears our government is weaker and spineless than I had at first anticipated. My thoughts are with Gary and Janis [his mother]."
Okse tweets: "Dear USA, if Gary McKinnon broke into your security system do not punish him, work with him to make your security system better."
Brelson is urging people to express their objections in a letter to their MPs.
The blogger's sample letter says: "I and many other voters had hoped that, under Gordon Brown and Barack Obama, the relationship between the US and the UK had progressed from the arguably dark days of the mid-2000s, and that sufficient trust now existed for the US to allow Mr McKinnon's trial on British territory and under British laws.
This decision suggests otherwise and condemns a vulnerable British citizen to a disproportionately long confinement period, thousands of miles from his family in a notoriously violent prison system. The moral case for this is indefensible even if the legal case is not."
Chris McNamara from Chicago gives rare dissenting voice. He says: "Gary McKinnon, if you didn't illegally access U.S. Gov. computers in the first place you wouldn't be facing extradition! You deserve this!"
There has been no word from the prime minister's wife Sarah Brown, a usually prolific Twitter user, who expressed her support for McKinnon earlier this month.
The Conservative party were quick to pick up on the anger. The shadow home secretary, Chris Grayling, put out a statement on the party's website saying: "People are right to be extremely concerned about our extradition arrangements."
But he stopped short of saying that any incoming Tory government would block the move.
"Ministers should hang their heads in shame over the Gary McKinnon case" said the LibDem home affairs spokesman Chris Huhne.
There are at least two petitions, here and here, on the Number 10 website, urging the prime minister to revoke the UK's extradition agreement with the US in the wake of the McKinnon case.
There is also a global petition against McKinnon's extradition.
