ReefGuy:I'm not confusing the issue. I understand that the situation you are referring to was a client response and was indeed more serious than just turning off their air, but the similarities between that incident and your response in the other thread about turning off your client's air are chilling.
I don't know how the laws work in Mexico, but if you escalate the situation into a life threatening one then you become responsible as well. If they refuse your order to come to the surface, don't make the situation worse than it already is. Handle it on the surface. That's what the laws are for. Not for you to take the situation in your own hands.

I did not and would not have turned his air off. You're taking this WAY out of context. I didn't say I would turn his air off if he refused to go to the surface...read it again. Besides, that was a totally hypothetical situation IF (again that is in capital letters) the situation had become a life threatening one to me.
