At one level, the number of ‘powers of entry’ are quite worrying with the implication that some ‘authority’ can simply barge their way into your home etc etc.
However, in practical terms, these powers of entry seem to be rarely used. Provided that you live an averagely normal life and don’t do anthing illegal or commit any act that might bring you to the attention of the ‘powers that be’ then surely officials won’t need to kick in your front door and force their way inside.
I fancy that this is yet another Media scare story playing to the inherent paranoia of some people.
