"This is going to cause me trouble, big trouble," the Chief wailed. I knew he meant with the protection boys. They did not like punks getting arrested and guns going off without their okay. But Ned thought the Chief had other worries and rushed in to put them right. "There will be no trouble. At no time did I violate any of the Robotic Restriction Laws, they are part of my control circuits and therefore fully automatic. The men who drew their guns violated both robotic and human law when they threatened violence. I did not injure the men—merely restrained them." It was all over the Chief's head, but I liked to think I could follow it. And I had been wondering how a robot—a machine—could be involved in something like law application and violence. Ned had the answer to that one too. "Robots have been assuming these functions for years. Don't recording radar meters pass judgment on human violation of automobile regulations? A robot alcohol detector is better qualified to assess the sobriety of a prisoner than the arresting officer. At one time robots were even allowed to make their own decisions about killing. Before the Robotic Restriction Laws automatic gun-pointers were in general use. Their final development was a self-contained battery of large anti-aircraft guns. Automatic scan radar detected all aircraft in the vicinity. Those that could not return the correct identifying signal had their courses tracked and computed, automatic fuse-cutters and loaders readied the computer-aimed guns—which were fired by the robot mechanism." There was little I could argue about with Ned. Except maybe his college-professor vocabulary. So I switched the attack. "But a robot can't take the place of a cop, it's a complex human job." "Of course it is, but taking a human policeman's place is not the function of a police robot. Primarily I combine the functions of numerous pieces of police equipment, integrating their operations and making them instantly available. In addition I can aid in the mechanical processes of law enforcement. If you arrest a man you handcuff him. But if you order me to do it, I have made no moral decision. I am just a machine for attaching handcuffs at that point ..." My raised hand cut off the flow of robotic argument. Ned was hipped to his ears with facts and figures and I had a good idea who would come off second best in any continued discussion. No laws had been broken when Ned made the pinch, that was for
