A few years ago, some divers talked their way into an extremely advanced cave system owned by the NSS-CDS (National Speleological Society-Cave Diving Section). They told management that they were going to do a good deed by cleaning up the site. They were not going to dive, they said, because they were not remotely qualified for that dive.Unfortunately, when it comes to grieving families, too often all moral and legal standards are thrown out the window.
Well, they had lied, and after the resulting fatality, the family sued the NSS-CDS for believing the lies and allowing them on the property. The suit went on for years, and it nearly bankrupt the NSS-CDS before it was over.
