Grouper vs Spearfisherman

http://news.yahoo.com/s/nm/20060912/od_nm/fish_dc_2

Back in the Philippine Islands, my dad's good friend died the same way. He was known to spear Groupers the size of a Volkswagen bug (I never saw pics - but my dad said he was credible)

Any mention anywhere of whether or not the diver was packing a dive knife?

A dive knife is a must for me after being tangled in the kelp in Timber cove and nearly shallow water black out after freeing myself. Freaky stuff...with out the knife I may not have came up at all! 

According to this article, these fish are "no-take".

It appears that the jewfish (goliath groupers) are over-populated and can get aggressive.
Truth will never be known if he acted in self-defense, mis-identification or poaching. But he doesn't deserve to die regardless. It's a tragedy. Always carry a knife, always!
