I think that Cindy made such a big deal about the pool ladder and the sheds being locked because she was trying to cover herself and George from any kind of neglect charges. They might have left the ladder there all the time, but she insisted that the ladder was always put up when not in use and the sheds were locked to protect the child because they were such wonderful caretakers of her. Seems like she was setting it up so that everyone, especially LE, wouldn't even THINK to question them about any involvement with the missing child, they would just automatically assume that such good, caring, careful grandparents couldn't possibly be involved! JMHO
