War - Where Are the Killer Dolphins?

Cathy Sorbo recently wrote about the military's use of animals to battle "aquaterrorism." And it reminded me of an interesting story that blew out of Hurricane Katrina. Thirty-six killer dolphins, armed with deadly darts allegedly escaped their enclosure during the hurricane and were roaming the Gulf of Mexico.

Though it was reported in The Observer, a casual inquiry is difficult for establishing the verity of the story. A quick Google search found the original article, but also a plethora of sites, such as Snopes, which claim that it was all a hoax.

Unfortunately, my current internet research skills impede me in establishing the actual truth, as well as filtering through the thousands of search hits to find the outcome of the tale. Any suggestions on how to efficiently get to the bottom of this would be greatly appreciated.

Anyway, true or not, it's a great story.
