"Questionable people" is hardly a concrete descriptor, nor is it something immediately obvious.

Let's say I meet a guy at a party. Facial scanners detect me with him. He seems like a nice guy, but he is currently on trial for a number of white collar offenses -- I know none of this. "The machine" does and will now assume I hang around questionable people.

The chances are just as good - not necessarily 50/50, but close to population baseline - that the person you met actually was a nice guy and "the machine" assumes you hang around with good people.

If your chances are actually higher than population average to hang around with bad people, the machine is probably correct for assigning you a higher risk.

Which all misses the point that as soon as he walked into the party, your own ocular implants would have performed the same recognition and you would have known to stay away from him.
