This happened in Lakewood, the city by me that recently banned pits. I know the cop - he used to be a Parole Officer with me. This dog is obviously a boxer, but they keep saying it was an aggressive pit bull. There's a story, but the video is disturbing, though the taser camera is conveniently (?) covered up before they tase the dog.
