Facewatch ‘thief recognition’ CCTV on trial in UK stores - BBC News

At the Download music festival in Donington Park, Leicestershire, police used cameras connected to NEC’s NeoFace system to scan music fans entering the arena to see if their faces matched a specially created database of criminals known to target festivals.
It sparked controversy and an angry on-stage protest from the band Muse, who accused police of “scanning our faces without telling us”.
But Simon Cole, Leicestershire’s Chief Constable, says the anger was based on a misunderstanding.
“Afterwards, there was lots of noise that we were storing images of people and we had 75,000 images… it just isn’t how it works,” he says.
Face-recognition camera systems should be used by police, he tells me.
“The technology’s here, and we need to think about what is a proportionate response that respects people’s privacy,” he says.
Go shopping in Leicester, he says, and you’ll be filmed by any number of CCTV cameras.
“If that checks that I’m a reasonably law abiding citizen, that doesn’t bother me,” he says.
