These things will be used by law enforcement. Deploying these and having remote cops surveil is cheaper than putting a cop on every corner.

The implications for a surveillance society are pretty intense though, but it can easily clean up tough neighborhoods where deterrents are necessary sadly.

I can also imagine pull over stops where the robot engages the passenger first, and is only equipped with a taser. You basically take the human out of the equation so there is no fear of getting shot by the officer or the passenger.
