Balko has this over at his place.
Seems like there is a turf war over the Nevada State Troopers drug dog program. Current and former thugs are alleging that that the dogs are trained to "alert" on a cues. Not actual drugs.
The dogs were being trained to alert their handlers by cues, instead of by picking up a drug's scent by sniffing, the complaint said. When a dog gives a false alert, this resulted in illegal searches and seizures, including money and property, the complaint said.
