Hmmm...GADiver posting videos for "friends"- yet putting the site up here - would not be what I considered "responsible'. Sometimes, it's what you don't know you don't know that gets you in trouble. Sometimes not knowing the risks, while something may "look easy" leads to a potential body recovery. A few years back, I was in Key Largo, and some divers lost their lives doing a penetration dive on the Grove. I seem to recall none were trained in it. Lack of knowledge of silt-outs, lost line recovery, etc. can lead to full blown panic and, sadly, loss of life.
Yes, people think "thrill seekers" assess the risks. Maybe, maybe not. As a for-instance, people doing full cave penetrations without the requisite training may get lucky. Not knowing the rule of 1/3rds, not having a redundant system, not having the proper lights, etc. doesn't mean you might not do a few dives safely. But risk analysis is all about what happens when things do go wrong, then developing procedures to minimize that risk as much as possilble. But to blindly say that the "cave diving community" has a lot of unnecessary rules is kind of an ignorant statement. If you look at the cave death statistics, they have dramatically gone down for trained divers. The same cannot be said for others (and I am including penetration diving in this group).
Sadly, the bodies that have to be recovered do nothing but endanger other's lives. Is this worth posting the video to puff up your self-esteem, or for bragging rights? Sorry, but I think such attitudes are both ignorant AND stupid.
