Insurance should never be used as a license to dive in an unsafe manner or otherwise behave recklessly. That's an abuse of the system and will cause all of us to have to pay more. It's hard to accept in this entitled society, but accidents should be the exception, not the expected. While there are exceptions, when diving, you and you alone are responsible for your own safety. Remember, you can call a dive at any time, even before you splash. There's simply nothing down there worth getting, hurt, maimed, or killed over.
Well, from the comments on a post on the DT FB group, some people are now questioning diving at all. These appear to just be recreational vacation divers from what I can tell. I wonder this event will result in some people doing more research about facilities at their dive destination and sticking to mainstream locations with better medical care.
