Likely before we get to robocops the "robocops" will be integrated into people who have proven risky by either previously known behavior in addition to social signals.

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.
