perfidy

Somewhere, in the murky, storm-tossed depths of the Gulf of Mexico lurks a killer. Intelligent, highly trained, and equipped with an arsenal of high technology weaponry. Trained to kill without mercy. And now free to hunt.

Who is this watery angel of death?

Flipper.

The United States Navy seems to have "misplaced" three dozen highly trained dolphin assassins thanks to the recent hurricanes. These friendly cetaceans have been used for decades for a variety of military missions since the cold war. Other dolphins have been trained to protect submarines in harbor, and a detachment was used for mine clearance in the Persian Gulf. The navy trained this particular batch of dolphins to hunt down and kill terrorists with lethal toxic dart guns attached to their snouts.

The hurricanes breached their compound, letting them escape into the Gulf. So if you are diving in the gulf, don't pet the dolphins. It may be the last thing you ever do.

However, if these are really smart dolphins, the first evidence of their depredations might be mysterious disappearances of tuna-fishing ships...
