I know plenty of experienced divers who have fouled up, gone in to deco and had a close call.

Generalizations kill as some of us choose to undertake being properly trained and prepared before undertaking a specific new type of diving (Deep, night, deco, penetration, etc).
I'm certainly not condoning it, it's just a statement of what happens.
Training is, to a certain extent at least, the generalisation of the previous generations "near misses". We need to acknowledge the positives of people survining those near misses - rather the prohibiting similar actions. Prohibition always leads to people breaking the prohibition. Anytime you take a group of divers out and say "You mustn't go deeper than 30m", there is always one person dropping their wrist so the computer reads 31m.
Deco is a relatively imprecise science, rather than prohibit divers going in to deco and blindly following their computer, I'd much rather we encouraged them to seek out appropriate advice and knowledge.
