Okay, here's what you do. Go down to the costume shop and get a dog's cop uniform. Now go down to the k-9 kennels and carefully sneak a dog out. Put on the aforementioned uniform. Put your holster, hat, walkie talkie and your badge on the dog (maybe add a nametag, just so they don't get suspicious) Send a memo to your boss before you send in the dog saying you're feeling a little ruff this morning. Use the aforementioned walkie talkie to keep up the ruse. Answer questions and stuff. We don't want to raise suspicions. When your dog's up to shoot, tell them "sorry, today I'm all thumbs" and try to get them to reschedule, if this doesn't work, then you now know the reason you used a police dog. Undoubtedly he will be a master marksman, having gone through rigorous training, and be able to shoot for you, passing your test. Relax, and spend the rest of the day playing destiny while your doggie-double takes care of the loose ends. The perfect crime.
