It would be a good idea for we who care about the ocean and all its creatures to video these guys, complete with close ups of their faces and license plate numbers and turning it over to the authorities. Maybe even post it on the Internet, forward to all dive shops, all diving groups, TV stations, etc. Make any restaurant that supports this poaching known so the public knows where not to patronize. Stop the money source.
The power of video can be quite remarkable.
Maybe this will increase the pressure on these guys legally, support network, public pressure, employers may see it, dive shops will see it, restaurants will see it, friends, family, organizations will see it. I am sure their family, friends, neighbors, church or other organizations, employers etc. would not approve of their illegal and immoral activities.
YouTube it.
