I see this as orchestrated outrage and not too different from the whipped up outrage over the Danish cartoons.

Both brouhahas being stirred up some number of months (teddy bear incident was in September) after they originally happened.

British outrage (at the absurdity, at the miscarriage of justice, at whatever) plays exactly into the Islamist agenda.

Plus, I think foreign nationals inside Sudan (even innocent schoolteachers) are personas non gratas and any excuse at all to deport them will be used.
