26/11 terrorists had free run for 28 hours: Book

The book 'The Siege' written by Cathy Scott-Clark and Adrian Levy says, India received 26 intelligence warnings (including from the CIA), months ahead of the 26/11 attacks. Stating that the four terrorists at the Taj Hotel remained almost unchallenged for 28-hour, it also narrates the political dithering that led to delays and how some policemen simply fled the bloody-scene.
