San Francisco, Washington & New York have turned to fish in their battle against terrorisme. To find out as quick as possible if terrorists have poisened drinking water, breams (picture) have been put in the water tanks.
The breathing, swim patern & heartrate of the bream are monotered with sencors. Any deviation could point to poisoning.
There is no electronic sencor that can spot poison as fast as the bream, says Bill Lawler. He is the co-founder of the Intelligent Antomation Corporation, wich sells the system.
Electronic systems can only detect types of poison wich they are programmed for, but the bream can spot any kind of poison.
