Never mind the loss of a life, the dog may well have “cost” more than a police car in training, and so on.
There are two basic kinds of people in this world; those who respect life, and those who do not.
According to the hippified Antiyuppie, ranchers and farmers must be awful people because they kill animals, and hunters must be the scum of all scum. That thinking is foolishness.
It is not a cause for celebration that some police mutt was shot, but it is not anywhere near “Murder” as another hippy poster pontificated. Dogs are not of the same value as humans
If departments put in even minimal effort into training their mutts to reduce the strength of their bite on a non resisting subject their might conceivably be more sympathy when departments lose a mere animal. But law enforcement doesn't put that training in, and too often the critters zero in on an innocent party.
So in a way you are right. I shouldn't have compared the loss of the mutt to the loss of a police cruiser. I should have compared the loss of the dog to the loss of an unreliable rebuilt police cruiser.
