Never gonna happen. Civil law does not work that way.
My mom works for lawyers who've done it successfully. Dude was at his apartment, apartment had "No weapons" clause in its contract, dude got capped in the parking lot and died. Dude's family sued the apartment on the grounds that if they don't allow people to defend themselves they have the duty to provide it. They won. This was in Texas.
Believe it or not. Agree with it or not.
