Face recognition police tools 'staggeringly inaccurate'

The accuracy of police facial recognition systems has been criticised by a UK privacy group. Two forces have been testing facial recognition cameras at public events in an effort to catch wanted criminals. Big Brother Watch said its investigation showed the technology was "dangerous and inaccurate" as it had wrongly flagged up a "staggering" number of innocent people as suspects. But police have defended its use and say additional safeguards are in place. Police facial recognition cameras have been trialled at events such as football matches, festivals and parades.
