Lets all take a few deep breaths and step away for a sec. In the end, the bottom line should be that OW divers need better training and this forum is allowing for different ideas to come up.
(Emphasis mine)
Need. That word often immediately precedes government intervention.
I do not agree that OW divers "need" better training.
The facts are that a very small number of divers have serious complications from their diving, taken as a whole against the diving population and the number of dives.
Very few people die, in truth, from their diving activities.
DAN shows what - roughly 100 deaths annually? Out of how many dives? We don't know. If we count only US deaths, the number is quite a bit smaller; let's say that half of all deaths are US citizens (probably about right.)
If there are 2,000,000 US divers in total and 50 deaths among them, the risk of death, annually, is 0.005% for a diver.
That's one in 20,000.
To put this in perspective, there are close to 50,000 deaths in automobiles in the United States annually. If we assume that essentially all of the 280,000,000 people in the US travel by car at some point in the year, there is a risk of death by car of 0.02% for automobiles. That is, its four times as likely you will be killed in a car crash as you will be killed diving.
To be more blunt about it, you are four times as likely to die in your car on the way to the dive boat than you are to die while actually diving.
Another data point. There are roughly 500,000 deaths every year due to heart disease in the US. The risk of death by heart disease is 0.2% annually, across that same (US) population. Yet the behaviors that cause heart disease - primarily overconsumption of various foods and lack of activity, are not proscribed by law.
Do OW divers "need" better training? Clearly, from the statistics, the answer is
no.
Is better training always better? Against what measure? Against the measure of risk of death or serious injury? Is that not the participant's decision?
What level of risk is "good enough"?
I'd argue that we're WAY beyond "good enough" already, just from the statistics.
