The Wrasse touced on several aspects of diving, but without pointing to one specifically, and that is the fact that there is no one out there to police your persona diving habits, but that's OK.
There are no police in the depths of the oceans. You have been trained as an open water dive and have been given ADVICE to the limits of your training.
Should you desire to exceed the limits and scope of your training, then the results are laid directly upon your head. YOU are solely responsible for the consequences of any dive that you make, no one else in the world can MAKE you descend below the depths of the ocean. It is upon your head and yours alone.
If I sound crass, so be it, but that is a fact of life.
