Re: 100 per cent false positive rate

Passport control is much much simpler, you've got one stored photo (based on the passport being presented) and are comparing it to another live photo all the computer needs to do is be 90% sure it is a match (or pick your own tollerance). You also have to look at the camera just the right way, with perfect lighting, possibly no glasses, definitely no hats etc.

In comparison trying to match thousands of moving people wearing anything against hundreds of pictures, both of which might be poor quality is a really really hard problem.
