Submarines, ships and laboratories at the Kitsap-Bangor Navy Base in Puget Sound are considered vulnerable to attack by terrorist swimmers and divers. So the base near Seattle may be getting a new security patrol. Dolphins and sea lions have been trained to find swimmers and scuba divers who are in the wrong place at the wrong time and, according to the Navy Marine Mammal Program, attach ropes to the suspects, who can then be reeled in for questioning.
