Overkill - three spears visible and stabbing a Tiger Shark - Spearo Craig Clasen
Then there are the bad: show off, consider sharks either a nuisance or a scared of them, spear for the photo or coverage, have no respect towards the ocean, pillage it as they please...
Craig Clasen and Ryan McInnis (and the others present) are bad spearos. Given a choice to kill or let live a large tiger shark (that supposedly put them in a life or death situation) they decided to kill it...a process that took over two hours and various spears, stabbing, and drowning...a slow and painful death...it is obvious from their photos and quotes that these guys were very afraid of sharks. In the video you will notice that shark approaches the cameraman in a non-aggressive, but curious manner.

From one of Ryan's webisodes on his site he mentions "Come face to face with a 12’ Tiger Shark that snuck up on me this summer in Louisiana, clean out your wetsuit" - in the episode Ryan also mentions that "he saw the last thing a freediver ever wants to see" referring to the Tiger Shark...
Craig looks pretty happy here with Tiger Sharks tail and jaws - no remorse as he stated
And if you truly respect sharks, as they say they did, they would have never let this get out to the media...they were looking for their 15mins of fame, media coverage, money and status among the spearo community...they have done the opposite, not only giving spearos around the world a negative image, but more importantly the chance for the media to take a stab at sharks once again.
I am sure you will see another post on this very soon from my old man - he is on way to South Africa at the moment.
