I think we've heard well from both sides. I think both sides have been well articulated here so someone can make an informed decision.
If you show your professional card, maybe you will be brought into litigation, maybe not. If you show the lowest certification card you need for the dive, maybe you will be brought into litigation, maybe not. Maybe a lawyer will find your highest certification and allege you should have acted, maybe not.
MargaritaMike shared his personal experience. I think everyone should take that into consideration.
In the end, the American litigation system can be summed up by one of my favorite Far Side cartoons:
For me, if something bad happens during a dive, and I can safely try to help a diver in need, I will do so based on my training and ability. Afterward, my certification levels will come out if I in fact stepped in. If I get sued, I get sued. It's a risk I'm personally willing to take. I would not be able to live with myself if someone was in trouble, I had the training and ability to help, there was a need for my help, and I stood by and did nothing. I have some experience dealing with emergencies that I can draw on. Others may not. YMMV
