While we're here, let's go the full way and set up a proveable and public way to train a robocop, and I'd trust that more than a human cop. The awkward moment when AIs have more brains than cops (at least under the US system).
So Jane truant with convictions of petty theft or battery gets off with probation if she agrees to embed her own personal "robocop". Yes invasion of privacy, etc. But the alternative for her would be time in the pen, for example. So in this case people can become their own robocops who turn the host in to authorities if certain conditions are met (engages in previously restricted activities).
I think this is more likely than a roving robotic cop which looks out for misdeeds.
