As robotic labour and utilites became more prevalent in the new century, so to did law enforcement. Pictured is one of the Rover 2000X series PatrolBots, with the Nueva Manchester's Polizei RIG. Serving with the Robotic Interdiction Group, RIG503 ("Rex") serves faithfully with his partner/handler, Officer Jack "Ketch" Kerkham.
Rex is halfway between a mecha with the intelligence of a dog, simple speech patterns and a tank. The RIG Officer's uniform is very much styled after the London Police's uniforms from the Victorian era - I suppose it's also a more light-hearted way of doing things than in PatLabor.
