A bomb scanner sold to dozens of countries around the world has been shown to be useless at detecting explosives, the Thai government said, raising the possibility that thousands of lives have been lost to bomb attacks because of ineffective screenings. The Thai government announced Tuesday that the GT200 failed rigorous tests carried out by scientists and the army in Thailand, after concerns were raised that the device was an elaborate hoax.
"We've done a double-blind test where the equipment was only successful in discovering in 20 percent of the cases, when just a random choice would give you 25 percent -- so there's no statistical significance to having the equipment," Thai Prime Minister Abhisit Vejjajiva told CNN.
The device's manufacturer, Britain-based Global Technical, disputed the tests' results.
