Exactly. I have friends who live in the Coeur d'Alene area and frequently take their dogs on short car trips and leave them alone in their cars for a few minutes, just as happened in this case.
The police officer who killed this dog claimed that it was "a vicious pit bull." Here is a picture of the dog (a labrador retriever):
The officer further stated that the dog lunged at his face through an open car window. Here is a picture of the crime scene, showing the window down only part way to allow for ventilation for the dog while it waited in the car.
I personally disagree strongly with Anonymous' tactics of naming the involved parties, especially if they include home addresses and names of family members. But, I don't disagree with them that the police department closed the book on this one prematurely and without accountability for the officer involved. That officer has, in my opinion, clearly demonstrated that he's unfit for this job and a danger to the community.
