Re: If the police won't be using facial recognition...
That's an interesting point.
What's to stop Google / Facebook setting up commercial private camera operations?, which capture faces at events like Glastonbury, Notting Hill, that cross-reference (using facial recognition) those captured images to Google / Facebook profiles photos, and then 'conduit' that data, package it, and sell it to advertisers (or Government).
A sort of "street view" on specific days, to see which of its users attend certain live events.
If you're carrying an Android mobile, running the Facebook app / Google and have location services on, I suppose you're already giving them this information, but it could be also used as a secondary validation of Facebook accounts to user profile images.
