Arm of the Law

A dusty Mars outpost just got its first police officer, and it's not human. When a prototype robot cop arrives in a crate labeled 'FRAGILE,' the rough frontier settlers of Bradburton figure they'll get some time to adjust to their new mechanical superior. They're wrong. The robot has protocols, procedures, and zero understanding of frontier psychology. It also has a law enforcement arm capable of handling anything the Martian desert can throw at it. Harrison's early gem plays delightful variations on the fish-out-of-water formula: a machine designed for order lands in a place where chaos is the local currency. The comedy emerges from cultural collision, from the robot's earnest literalism and the locals' schemes to exploit it. But there's an edge beneath the humor, a question about what 'justice' actually means when you remove human judgment from the equation. It's slight but sharp, the kind of story that makes you grin at its premise and think about it afterward.
