The officer's own comment that he was not going to send the dog off to be checked because it was not a threat to anyone says it all. He went out and killed a pet dog. It's nice to know that instead of trying to assist someone's pet, he just believes in killing them if there is a problem. It is really a contrast to stories you hear about people who actually care about animals and are out trying to rescue them from situations. Guess he didn't want to get his hands dirty or his feet wet.
