Johnny Boy, "The Enforcer", is temporarily in the clear over the cock-up in his "unfit for purpose" Home Office - having deployed the old blame-someone-on-the-floor-below tactic. That whole affair has had the chattering classes demanding to know why criminals weren't safely processed onto databases.
Hey presto! When everybody's clearly apprised of the importance of databases, John Hutton steps in with the notion of a cross governmental database, to solve all our problems.
He justifies this by pointing to a bereaved family contacted 44 times by his department. That rather suggests that his Department is run and staffed by numpties. It hardly gives an excuse for a giant database.
