Would Ms Rudd require that all door locks produced by locksmiths selling locks for use in the UK share a common master key, copies of which are stored in Ms Rudd's office, in all police stations (just in case), in the glove boxes of all emergency vehicles (just in case), in the cabinets of all utility companies (just in case), in the offices of local councils (just in case - terrorists and kiddie botherers y'know) and of course various very reputable* private security companies such as G4S (just in case one wants to outsource things).
