I think this is sarcasm, but I can't tell.
I'm no lawyer, but isn't this like a slip and fall thing...you couldn't sue Disney because your child fell off your shoulders because you chose to put them up there. Disney didn't create a dangerous physical condition that caused someone's child to fall off their shoulders. I mean they didn't create a condition in their parks that was hazardous that caused a child to fall off shoulders. If that were true, people could sue Disney every single time they did something dumb in the park and got hurt. Like if I walked around with my shoes untied and tripped and busted my head open. I think I'd have to prove Disney had some physical obstacle that was unsafe, that they knew about, and that they did nothing to remedy.
(sigh) And on another note, I wanted to eat some AK poop treats. Darn banning.
