This from John Redwood’s blog:
"On November 5th we remember that terrorism in the name of religion is not a new problem. We should also remember how this plot was foiled. It was not intercepted through the issue of ID cards. The police or army did not spot the plotters carrying huge barrels of gunpowder into a cellar. It was not prevented by a cordon of oak or iron – today’s concrete and steel – around the Palace of Westminster. The murderers were prevented from killing the Parliament and government of James I by intelligence picking up a family tip off."
