Police use of facial recognition is legal, Cardiff high court rules

The Guardian 

Police use of automatic facial recognition technology to search for people in crowds is lawful, the high court in Cardiff has ruled. Although the mass surveillance system interferes with the privacy rights of those scanned by security cameras, a judge has concluded, it is not illegal. The legal challenge was brought by Ed Bridges, a former Liberal Democrat councillor from Cardiff, who noticed the cameras when he went out to buy a lunchtime sandwich. He was supported by the human rights organisation Liberty. Bridges said he was distressed by police use of the technology, which he believes captured his image while out shopping and later at a peaceful protest against the arms trade.
