If that logic is true, then I guess that means that if the tenant has any other crazy thing in the home, I'm liable if one of their buddies injures themselves on that too.I'm not saying that isn't possible, but I am questioning how our legal system allows that kind of silliness to go on.A landlord should not be liable for any toy some tenant's friend hurts themselves on.

That lawsuit is a claim for fraud, and that’s what fraud typically is...a misunderstanding and someone being “injured” and wanting to hold the other responsible for it.
