"To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public." Theodore Roosevelt
The London bombers may have been duped into killing themselves so their secrets stayed hidden.
Police and MI5 are probing if the four men were told by their al-Qaeda controller they had time to escape after setting off timers. Instead, the devices exploded immediately.
A security source said: "If the bombers lived and were caught they'd probably have cracked. Would their masters have allowed that to happen? We think not."
The evidence is compelling: The terrorists bought return rail tickets, and pay and display car park tickets, before boarding _ a train at Luton for London. None of the men was heard to cry "Allah Akhbar!" - "God is great" - usually screamed by suicide bombers as they detonate their bomb.
Their devices were in large rucksacks which could be easily dumped instead of being strapped to their bodies. They carried wallets containing their driving licences, bank cards and other personal items. Suicide bombers normally strip themselves of identifying material.
