The latest people added to those who need to undergo security checks are to be parents who take a group of children to Youth Clubs or after school activities.  This is suspicion gone mad.  As author Philip Pullman says it is “corrosive to healthy social interaction”.  I am glad to say that the Liberal Democrat shadow Home Office Minister Chris Hunhe has come out strongly against such a requirement calling it, quite rightly, “a disproportionate response that risks deterring volunteers.”
