Joy of Joys ... can it get any better !!!
"D-PO would be capable of, for instance, tapping into facial recognition systems to alert a police officer on patrol to a suspect nearby, and can even offer advice on how best to apprehend the suspect."
According to current actual US of A policing practice that would be:
Identify ethnicity of suspect.
If not 'white' draw AI augmented weapon, point in direction of suspect, AI targets and fires weapon, arrest body and confirm Facial Recognition was correct !!!
[Sorry, but is this not the first steps to 'Judge Dredd']
