I have seen one, and it was on a school trip in 2004 in Durban where they brought one of the caught great White Sharks and dissected it in front of us kids for "educational" purposes, basically showing us what it has in its stomach, how it has infinite teeth. They use these "educational" dissections as justification for draglines and nets unfortunately.

I actually wrote an email to the new Minister of Forestry, Fisheries and the Environment: Dr Dion George, giving my two cents like how draglines and nets are outdated and dangerous to the shark population, how much better methods now exist. I only received an email saying they noted my concern. At least there are organisations really trying to save not only the great White shark but many other marine animals
