It sure is interesting how many people are so confident that what essentially amounts to a freak accident -- a tragedy that has NEVER happened on Disney property ever before (remember, people used to be allowed to openly swim in that water, like, for years and years) -- could never happen to them. Hell, *I* played on the shoreline on that beach as a child many times, often surrounded by other children whose parents allowed them to do the same. My parents were far from negligent.
These types of incidents always bring out the folks who want to pretend it can never happen to them, though. I think the alternative is too frightening to contemplate.
