A fascinating book! This book clearly shows there is no such thing as "common sense". Aaronovitch gives example after example where different views of events conflict, often both sides falling back on what they consider "common sense" to back up their arguments. Such as two planes couldn't have brought down the towers so there had to be charges places through out the buildings. Or, they weren't really planes but missles disfigured by holograms. He gives a recent survey of conspiracy theories starting with the Elders of Zion pamphlet from the beginning of the last century up to the Truthers and the 9/11 bombings, including JFK, Marilyn and Diana. In between he gives examples of less known theories, as well. This is a good book for skeptics.
