I read that armed undercover marshals are going to be deployed on the London Underground in an attempt to foil future bombers (Personnel-Today.com, 23 August).
What an interesting idea. But how are these marshals going to recognise a suicide bomber? And how are they going to stop one?
Is every carriage in every tube train going to have a marshal? If not, then how would they even know if someone jumped up in the next carriage and shouted: “I’ve got a bomb”?
A marshal on a plane is a totally different solution to a totally different threat. It sounds like a good idea, but it does not stand up to scrutiny.
