The mechanical Hound slept but did not sleep, lived but did not live in its gently humming, gently vibrating, softly illuminated kennel back in a dark corner of the fire house. The dim light of one in the morning, the moonlight from the open sky framed through the great window, touched here and there on the brass and copper and the steel of the faintly trembling beast. Light flickered on bits of ruby glass and on sensitive capillary hairs in the nylon-brushed nostrils of the creature that quivered gently, its eight legs spidered under it on rubber padded paws.

Nights when things got dull, which was every night, the men slid down the brass poles, and set the ticking combinations of the olfactory system of the hound and let loose rats in the fire house areaway. Three seconds later the game was done, the rat caught half across the areaway, gripped in gentle paws while a four-inch hollow steel needle plunged down from the proboscis of the hound to inject massive jolts of morphine or procaine.

One good thing about this is that it will be hard for them to justify deadly force in the case that a machine "feels threatened", but I'm sure there are some creative ideas being hatched in that area.

This will also lead to a dilution of the personal accountability and responsibility for bad enforcement actions. When the machines violate rights, there will be no person to whom culpability can be easily assigned. If the computer program is "approved", then nobody can be accused of doing anything wrong.

Sounds like a recipe for an even more violent society... stray bullets whizzing past robots and drones programmed to do the state's tyrannical bidding and flying into the streets.  Safer for law enforcement, but much more dangerous for your average citizen.
