Ha ha ha that's just another conspiracy theory
Why on earth would the British want to plant bombs in Iraq??
The guys were probably just bomb disposal experts, that's why their car was full of equipment..
Remember, the Brit media loves a good story and always print scandals like the mistreatment of prisoners in Abu Ghraib jail and other harshness by Coalition troops, then the soldiers are court-martialled and punished.
So if the two SAS guys really were bombers,the media would have printed the scandal all over the front page
