Pornthip was a vocal and sustained supporter of the
GT200, a "remote substance detector" that Pornthip and the UK manufacturer claimed could detect from a distance various substances including explosives and dead bodies. Several nations have found the devices to be fraudulent. 2008 clashes between police and the
Peoples Alliance for Democracy resulted in one death and several serious injuries, but much confusion as to whether the injuries were caused by police tear gas grenades or
improvised explosive devices carried by the protesters. Pornthip used a
GT200 device to conclude that the protester injuries were not caused by explosives and concluded that tear gas grenades caused the injuries, leading to the removal from office of the national police chief. Queen
Sirikit later attended the funeral of the fatality. Large protests against the
Democrat-led government were held in Bangkok in 2009, prompting a violent crackdown. Rumours of widespread killings were denied by the government, which pointed to the lack of bodies. When shipping containers rumoured to be filled with skeletons were found sunken off several coastal areas, Pornthip was assigned to help with the forensics. She suggested that rather than opening up the containers, GT200 bomb detectors using dead body "sensor cards" should be used. When news of the fraudulent nature of the
GT200 devices became public in 2010, Pornthip defended the use of the devices, even if they were proven ineffective. She noted, "I do not feel embarrassed if the bomb detector is proven ineffective. Personally, I have never handled the device myself. But my people have used it and it is accurate every time. Long long time ago, people believed that the Earth is flat and anyone who said otherwise faced execution. Things which are not visible does not necessarily mean they do not exist." == Media personality ==
