I was dumbfounded when I saw that interview with Nancy Grace. And who the hell was that dumba$# instructor. You can't get bent from 50 feet of water. What scuba class did you take? You can get an AGE in 5 feet of water you morons. Oxygen. Last time I checked, 100% O2 underwater is toxic. That's why we breathe air underwater...or we breathe nitrox which allows us to modify the percent of nitrogen so that we don't absorb so much nitrogen when diving.
And what's with the "all they had to do was press that buoyancy thingy button and shoot straight up to the surface." Remind me never to go diving with either of those imbeciles. The instructor was an expert witness. Hmm. An expert of what. That instructor kept saying "see, just push the button right here, see right here...that's all they had to do."
These people sure gave the sport a bad rap. If I was a prospective student, after watching these dumbbells, I would think twice about scuba diving.
According to your profile you're a divemaster. I would suggest you either take some classes over again or never, ever actually work as a divemaster.
