I believe that LCY operates a two scale system so that during the flying period it operates an RZ but outside of those hours it is merely a CZ only requiring random checks of ID badges. All aircraft must be searched or sealed if present during the change from one zone to another. It highlights once again what most of us are only to aware of in the airport industry that many of the security operatives are not managed nor supervised well enough. The Dft must also take the blame for this only conducting tests normally during office hours (the staff being civil servants). As for the armed Police they have little input into the airport security and are merely there to deal with the possible armed attack. Unless they observe the punters they are not much use looking away and I am sure they are not trying to intmidate anyone they are probably bored. Considering the location, the fact that the average pax earns in excess of £85000 it is most unsatisfactory.
