Computer enhancement would help, but its hard to make a silk purse out of a sow’s ear so to speak.
I think you’re right though - I think that the P&S pair know that the good guys (MI) know. I mean, if someone showed me an obscure picture of myself crossing a street somewhere, I’d likely remember it. And if I was up to no good, I’d be getting a bit nervous.
Doesn't have to be that good, P&S already know it is them. It was probably good enough since those two were probably under surveillance by the good guys anyway, or even the bad guys checking out their affair, then losing control of their material.
