Is Britain that much a police state already?

Is Britain a police state? No - and facile comparisons like this do nothing except underplay the repressiveness of real police states. As for the cameras, a significant proportion are broken (or fake), and there is hardly anyone watching the output of the remainder. They are mostly for show, as a cheap way for local councils to pretend that they are dealing with low-level crime. vandalism etc, without actually spending real money. The only cameras that actually do anything of significance are the road traffic ones - and that is because they can be largely automated.
