The dog probably barked at him which was scary to him or maybe annoying so he protected himself the only way he knew how. He was in fear for his life or maybe his hearing. Dogs bark as a warning to the intruder but also to alert their humans. Most dogs don’t bark a lot before attacking if they do attack. The cop did it to be mean because he could and would get away with it. The people who called the cops are just as responsible and are probably assholes.

He may have been in fear for his hearing, so he fired four shots from his gun.
That’s good reasoning right there, I tell ya. You are cop material for sure!
