I agree with H2O Gal's post and I think the statement
Personally I know I have chosen a sport that can potentially result in death is a big eye opener!
What sport cannot potentially result in death? I run almost every day. I can die of a heart attack, a stroke, a car can run me over? Who should be sued? Nike, for giving me the tools to kill myself with? (In the case of being run over there will be an issue of whether I should have been running where I was or not or whether the driver ran me over at a crosswalk).
I have seen with my own eyes two cases of theoritically fit and able people dying in the gym. Neither the gyms or the fitness monitors were sued.
Maybe we really need to get the statistics out of how many people die or are seriously injured doing what?
In comparison to other sports, the incident rate, per number of participants, is much lower than many other sports. For example,
cycling has an
injury rate of seven times that of diving. Even golf carries 1.5 times the risk that diving does, according to the U.S.-based National Safety Council, which figures accident rates based on reported incidents and approximate number of players. Percentage wise the NSC publishes these figures for sports related fatalities:
Football 2.17%
Baseball 2.09%
Basketball 1.86%
Soccer 0.91%
Volleyball 0.37%
waterskiing 0.20%
Raquetball 0.17%
Tennis 0.12%
Swimming 0.09%
Bowling 0.04%
Scuba 0.04%
So on the question of not showing a DM or instructor level certification because of liabilities I think it depends where you are and the way the law works in each country.
Certainly in Europe I think it's the other way around from the States. By
NOT saying you were an instructor, at least to the LDS, you may well be found at fault. There would also be a question of whether you are in teaching status or not. If you are not and you say so, then you're probably,
from a legal point of view, just another diver who happens to have passed an instructor level exam. If you
are in teaching status and you choose
NOT to inform the LDS where you happen to be diving for fun and something goes wrong and you are
involved, then the authorities are going to want to know
why you chose not to inform the staff that you were a teaching status instructor. It will look very suspicious and as if you were withholding that information for a reason.
To claim that you withheld the information because you just wanted to enjoy your dive...
