So how long until this spreads to the U.S.A then?

The Children’s Secretary set out £400million plans to put 20,000 problem families under 24-hour CCTV super-vision in their own homes.
They will be monitored to ensure that children attend school, go to bed on time and eat proper meals.
Private security guards will also be sent round to carry out home checks, while parents will be given help to combat drug and alcohol addiction.
Around 2,000 families have gone through these Family Intervention Projects so far.
But ministers want to target 20,000 more in the next two years, with each costing between £5,000 and £20,000 – a potential total bill of £400million.
"Responding to stories claiming that irresponsible families will be monitored by CCTV cameras in their own homes, a DCSF spokesperson said: Families will not be monitored by CCTV in their own homes. Through Family Intervention Projects (FIPs) we are supporting and challenging the small number of families involved in persistent anti-social behaviour. FIP workers spend time observing families in their own homes, helping them to recognise that their anti-social behaviour is unacceptable. They focus on the causes of their behaviour, and challenge them to make changes so they can turn their lives around. A very small number of families who need further intensive support are placed in residential units with project workers living with them – this does not involve CCTV. This is part of the Government’s approach to preventing and tackling anti-social behaviour and youth crime. In the last year alone, FIPs have challenged and supported over 2300 families to turn their behaviour around. Twelve months on from the Youth Crime Action Plan, Ed Balls and Alan Johnson have written to all local authorities in England asking them to expand and accelerate FIPs. Councils and police have reported that FIPs are an excellent way of preventing and tackling crime and anti-social behaviour."
