then that ONE person can be punished to the full extent of the law.
it applies for any pet. if it gets loose and hurts someone it should be YOUR responsibility. i dont care if 5 other people around you own a tiger/dog/wolverine/whatever. you should be allowed to keep whatever you want, and only you should be punished accordingly if something bad happens, not any other person who keeps said animal
extenuating circumstances such as a brain tumor are not the issue here. its the perception of "dangerous" pets. a brain tumor is 150% out of the keepers control. keeping your pet that you know "could" harm others safely kept, is the issue
