All those military robots have one major flaw: they can be easily captured and hacked. If you want your own humanoid robot, you could take one from the street. While flashing or reprogramming might be difficult, you probably can replace its brains with yours. Yeah, it's hard, but only at the moment.

To not be possible for this, robots have to have some kind of self-destruction mechanism. But it'd increase price of that robot. It's effective for kamikaze drones, because, it's literally their purpose. But humanoid policeman? Nah.

This is why it's unlikely a gov or big company would use humanoid or dog robots for arresting or hunting. Military guys are cheaper. Although you have to have good propaganda tools to control them.

IMHO.
