I'm actually surprised horses are still being used by law enforcement because they're retarded animals who can be easily spooked and kill someone, but then I remember police use them for that exact purpose and to shed responsibility if it happens.
We can also make devices that detect specific particles in the air in the tiniest of ppm, but cops use dogs' noses instead. Less accurate, lower precision of specific particulate, but the handler can amp up or calm the dog down to give false positives or negatives on command.

You think police officers cared about being accurate?
