I doubt this very seriously.
If I look at the latest PADI numbers, they claim to have 130,000 "dive professionals" worldwide and 6500 or so stores and resorts. They dont say if thats active people or old farts like me.
Assuming 30,000 of the professionals are active instructors, and the last time I checked (which has been years) to remain active you had to certify 6 students per year. Don't know if thats still the case, but if so, that means about 180,000 students a year, if each does 4 dives in a class, thats about 3/4 million training dives a year, and thats just PADI. I know some classes don't do 4 dives, so lets just say 400,000 training dives a year.
Linnea Mills' accident was an act of idiocy. Rather than promoting diving by pointing out, what I think, is a stellar safety record (all things considered) you wave around Linnea Mills and tell the OP that he needs another instructor. That's just ridiculous.
@boulderjohn- avoid teaching hospitals. Surgical interns and residents perform surgeries under the direction of an attending surgeon every day. You know, they have an instructor watching them perform skills.
