Where else are you going to hear somebody say, "Unless you can say, 'Stop biting my f***in' leg in Dutch,' you'd better stop resisting."
Or see a K-9 handler announce that he's going to deploy his dog only to realize that he'd left the dog back at his Bureau? (Ever heard a K-9 handler impersonate his dog over a P.A. system? It's great.)
Or hear about the K-9 handler who put his dog into the backseat of his patrol car - not knowing that another deputy had accidentally put a detained suspect in the same backseat moments before. Hopefully, it wasn't one that cops had recently fed a Hershey's to (Don't cops know that beyond making the dogs shit like there's no tomorrow, chocolate is toxic to 'em?).
I also appreciate the inventiveness with which dogs have been deployed. One of the more inventive uses of a K-9 was when a detective I used to work with, Jlot Inglis, used one to identify a suspect who'd stolen data from a computer. He had a K-9 pick up the scent and follow it to the employee's cubicle. Case closed.
They've been used to track scents from ballistic casings to gang members' houses. When one leapt onto the lap of one incriminated defendant, he simply said, "If it was a man, I could kill him. But what am I going to do to a dog?"
