I can see how this would lead to a lot of false positives.
We may be a nation besieged by CCTV but its terrible quality CCTV, with a conviction rate that hardly ever sticks without facial recognition.
Honestly as long as its not in my home, I'm all up for high def cameras everywhere.
My neighbours car was just stolen from beside mine last week, in our private car park, in broad daylight.
They bust in and recoded his keyless entry in about 3 minutes.
