Unfortunately, there's a misconception underlying this one that there are 'good people' and 'bad people', and the role of Government is to protect the former from the latter. This of course flies in the face of the reality that crime is committed by otherwise ordinary people under extraordinary circumstances.

Under this rhetoric - widely subscribed to by the right wing and tabloid press, it seems a logical step that the role of Government should be to impede 'bad people' as much as possible - "If you have nothing to hide, you have nothing to fear" is an obvious corollary from this position too.
