Devil's advocate. The "owner" of peanut was taking in wild animals without permits. Never bothered to even try.. They find peanut who bites an officer. Now that officer can just take this weird dude's word that peanut is not rabid, or he can wait till he's symptomatic, at which point he's dead. The only fast way to test for rabies is with brain tissue. It was either kill peanut or risk the officer drying of rabies.
Blame it all on the people who took in a wild animal without telling anyone and then exploited him for views
