Cris, you are concerned with safety, but there are many others who will advocate sensible sounding rules to enrich themselves. First. KEEP YOUR GOVERNMENT OUT OF DIVING. Figure out which shops/guides are ethical and responsible and teach them how to guide these dives safely. They will spend the money to advertise and differentiate themselves from the idiots. Be patient, this doesn't happen overnight. There are still some full 100% idiots guiding people in the Mexican caves.
