You reckon? I was thinking they would prefer a bunch of OC divers on the jury as they would be thinking "Hey, I dive, this is basically safe. If a guy died suddenly for no reason, it must have been an equipment failure."
Who exactly is "they"? Both sides have peremptory challenges. My guess is the other "they" will use them.
Florida's population is over 20,000,000. Exactly how many of those do you suppose are SCUBA divers? I reckon that the odds of getting more than one on a jury in this trial are slim to none anyway.
