This is far too complex for the UK to implement because we're all so fucking stupid over here.
Firstly, we'd have texts sent to the wrong people, causing people to go in to a frenzy for no reason.
Secondly, the checkpoints will be announced but no staff will be there to give out the notices.
Thirdly, the random phone calls/house visits will be at stupid o'clock as opposed to times when people are likely to be out i.e. the day.
Fourthly, you'd get people taking several photos of their houses way before going out so that when they get a phone call, they'll send the photos already taken.
