don't agree with Tuc. Any safety system needs a 'just' culture where those knowingly breaking the 'rules' are dealt with. Blaming the system for not stopping those who knowingly subvert the protections in that system seems illogical and ultimately impossible.
You'd spend inordinate amounts of time and money trying to double-think all the possible scenarios and you'd end up restricting the flexibility of the resultant system to a point where it is actually more dangerous by being rigid by design.
