NetDoc,
One thing about your last statement. When we take a breath of compressed air and go under the water, we take a risk... period.
Joe did the right thing. (Joe, I am glad to have met you. To be honest, I would not have thought of contacting the shop about this.) But, to say that we are eliminating risk is incorrect. You are looking at an instance of helping to mitigate it to a sane level instead of near suicide.
I wouldn't want someone looking at anything to do with diving and say that there is no risk. That is not only incorrect. That is an illusion. Air embolisms, drownings, and undeserved DCS hits still happen. Throw in physical types of things on the boat (my most common concern actually) just as cuts and blunt tramua and get a reminder of why every diver should at least get rescue trained. We can knock the risk down to near neglible, but we can't eliminate it without staying out of the water. Even if you do everything correctly, Mr. Murphy has still been known to make his presence known.
Looking at the standards of one agency that I train with... this kid would not have a C-Card. Safe attitude is written right into the standards and the attitude that I have seen this young man display here goes the opposite way of the reason that we take training. Realizing that we always have a risk goes a long ways having a better attitude.
