Re: Techies will continue to sneer.
"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).".
Y'mean like the TSA require all your luggage to have locks with master keys if you travel to the States?
Can't think what could possibly go wrong with that *stares at kits of TSA master keys for sale*
Don't forget, if you've nothing to hide you don't need privacy.
