Anyone can sue anyone or any entity for anything in America. When I took my CCW (Carry Concealed Weapon) course, the instructor reminded us that, even if you shoot a burglar in the act, he can sue you for damages to his health if he survives, or his survivors can find some way to sue you. Courts may not find you guilty, but it'll cost you a fortune in legal fees.
This year's AZ ballot carries a proposition eliminating perps' right to sue their victims for damages.
