The old adage, Monkeys And Peanuts.
You cant blame someone for not being able to be in two places at once, as it seems "security" staff would have to be to do their job properly.
However it appeared that some security weaknesses were through staff just not be bothered to,for example, check bags.Peanuts again I suppose.
What I think is most worrying though is that a group of individuals, calling themselves Managers, has been allowed to so obviously degrade the overall security cover at MAN whilst giving themselves salary rises.
