Absolute insanity. One of the cardinal rules of diving is don't touch ( or get too close) to any marine life.
This ranks right up there with something I witnessed in Yellowstone a few years ago. A mother grizzly was walking her two cubs along side the rode. Several cars pulled off the side of the ride for pictures. One tourist, however, got out of his car and started following the cubs at a distance of about 50 feet for, what I guess, was that National Geographic-like photo.
The mother grizzly abruptly turned, stood on her hind legs and growled. It is a wonder she didn't attack. Someone (

) reported the license plate of the driver to the park rangers. I heard later the errant photographer was escorted out of Yellowstone.
