Usually dolphins were controlled via signals transmitted through a neck harness. 'The question is, were these dolphins made secure before Katrina struck?' said Sheridan.

This is really interesting, but one suspects wildly inaccurate. Dolphins that are trained to shoot people? Really? Even if its true I find it hard to believe that the Navy would have left them armed as the storm approached. They tend to have fairly careful security proceedures.
