Two questions relative the HRP-4C:
Does stalking a robot constitute a crime under most nation's criminal codes?
Can a robot get a Restraining Order against a human?
I wouldn't think that stalking a Bot would be a crime no more than following a car is...it's what you do after you have stalked the Bot or car that matters...it's a piece of private property with ownership so if you damage it you can be charged to pay for it.
Until a Robot becomes a " sentient being "I for one hope that we never get so stupid as to give ourselves over to control of a machine of any kind , they are tools nothing more, advanced tools but just tools.
As far as a restraining order I think " DANGER KEEP BACK HEAVY MACHINERY OPERATING THAT CAN KILL YOU " should be restraining enough for most of us and for the others well you've heard about the "gene pool " thing.
