In this case it seems to have STARTED with stupidity, since the officer, at least from the story, misread the address on the warrant. I agree the police as a whole seem to be all to ready to shoot any dog, anytime, anywhere.
If he “misread” the address, he would have been apologetic, ashamed.
Note his reaction in the article.
“Misread” is now the “official excuse”, not the actual reason.
