Dog alerts are about as objective as UFO witnesses. Having trained multiple working dogs of multiple breeds, nonverbal communication between dog and human is very easy to establish.

Stopping people due to AI reports and having dogs smell them is kind of the problem everyone is concerned about.

That’s even worse, since K9’s have failed every independent test ever done on them.

They alert when their owners want them to, and make a mockery of the 4th.

You’re glossing over the fact that the dogs are trained to respond to the officers commands, and the officers can make a trained K-9 alert on any car.

Essentially parallel construction. Know their perp from other means, make dog alert on it, continue to abuse your power.
