Bush: 'We're doing all we can to protect America'

US President George W Bush has named Tom Ridge to head the new Department of Homeland Security, but said even the biggest government shake-up in more than a half century can “neither predict nor prevent every conceivable attack”.

“We’re doing everything we can to protect America,” Mr Bush said yesterday as he signed a bill creating the department. “In a free and open society, no department of government can completely guarantee our safety against ruthless killers who move and plot in shadows.”
