Fear is a wonderfully self fulfilling circular argument Labour were masters of. Remember how complacent we were during the height of the IRA bombings. People didn't behave in a way that allowed fear of an attack to control our lives. We just carried on regardless.
The main reason I am glad Labour are not in government is down to how much control they wanted over everyone. From ID cards to the fear used to make everyone think being against them was unreasonable. When in reality there are more than enough existing methods to track people.
BTW I have never been pro Tory either.
