Yep, several years ago here in Sacramento, we had some drunken, drugged-out lunatic throw a police dog off a bridge, killing it. But you don’t have to throw them off a bridge. In fact, you don’t have to be very strong at all to seriously injure a dog. It’s only because most people are scared to death of being bitten that allows police dogs (especially the lone police dog) to be effective. I’m very thankful for that!
That said, its amazing the number of urban, often non-white people who are petrified of dogs. Our cockapoo on more than one occasion caused some people to go into headlong retreat when she went up to greet them. Who knows how many sets of underwear would have been soiled if it had been a large working dog.
