Sir Ken pointed to the rhetoric around the "war on terror"—which has been adopted by Tony Blair and ministers after being coined by George Bush—to illustrate the risks.
He said: "London is not a battlefield. Those innocents who were murdered on July 7 2005 were not victims of war. And the men who killed them were not, as in their vanity they claimed on their ludicrous videos, 'soldiers'. They were deluded, narcissistic inadequates. They were criminals. They were fantasists. We need to be very clear about this. On the streets of London, there is no such thing as a 'war on terror', just as there can be no such thing as a 'war on drugs'.
Macdonald was saying this to whack at Blairite proposals to allow "the indefinite detention of suspected terrorists without trial, later held incompatible with human rights by the courts, and the replacement law that permits suspects to be placed under control orders instead of being brought to trial."
