[Roccus]

This dog may have had some shade when his handler departed, but the sun moves, so the areas provided with shade will change, or possibly disappear altogether.

Ya gotta remember, he is a "trained observer" and has to make split-second decisions! If that wasn't stated in his training, he's off the hook.

The question: will an internal investigation find the cop responsible for negligent homicide of a police officer?

Oh, never mind:

Copper will be honored in a memorial service - and his handler may face disciplinary action if the internal investigation reveals that there was not enough shade in the kennel when Copper died.

“If?” If? Already they’re covering for him.
