The point is Disney advertised those images and either changed the policy on entering water either swimming or wading or swimming was never allowed and they out those images out even with that policy in place. Instead of explaining that it is now dangerous with a warning dangerous wildlife sign, they felt a simple no swimming sign was sufficient. It is not because anyone there who could wade in previously if that was the old policy or who researched and saw those advertisements along with a very beachlike inviting environment would think the swimming was not due to wildlife dangers. They did not warn guests as well as they should have considering they had images like this out there as well as presenting it in every way as a family beach. I do not think the gorilla incident should lead to a lawsuit, I feel very differently about this incident. I am not kidding if you google searc GF beach there are so many images both perosnal (which I know are not disney endorsed, but shows how popular wading/playing in the shallows are and should be cracked down on) and via wdw/
travel agent sites with people in the shallows. I can see why people felt it was safe.
