Why Thailand Still Uses Discredited Bomb Detectors

Article excerpt

The governments of Thailand and Britain have deemed the GT200 bomb detector unreliable, but the Thai military continues to use it to make arrests in the Muslim south.

A handheld scanner that claims to detect bombs at a distance of 700 meters but has been described by British scientists as a scam continues to stir political controversy in Thailand.

The British-made GT200 scanner has been used for years by Thai troops battling a Muslim-led southern insurgency to check for explosives and locate bombs. But in a recent Thai government test, the scanner failed to detect explosives hidden in 4 out of 5 containers.

The test follows weeks of pressure by domestic critics. A BBC investigation last month into several UK-made portable bomb detectors found no scientific basis for their stated use. In response, the British government banned the export of one such device, the ADE 651 made by ATSC, to security forces in Iraq and Afghanistan. Britain has warned foreign governments that similar detectors, including the GT200, are unreliable.

(Read here how the Iraqi government spent $850 million on scanners manufactured for about $250 apiece.)

However, Thailand's military has insisted on keeping the GT200 and publicly defended its use. Its stance has fueled a political backlash over the procurement of hundreds of apparently dud detectors by the military and other security agencies. Opposition lawmakers and newspaper columnists have demanded that Prime Minister Abhisit Vejjajiva look into allegations of mark-ups in the price of the detectors, which cost up to $30,000 each.

Untrusted machines

In southern Thailand, where nearly 4,000 people have died since 2004 in a Muslim-led insurgency, soldiers have employed the GT200 to search vehicles, schools, and houses for explosives. Legal rights groups say that suspects have subsequently been detained since 2007 on the basis of positive readings by the device during mass sweeps by soldiers of Muslim villages.

"The people in the south don't believe in these machines. They don't trust them," says Angkhana Neelapaijit, who chairs the Working Group on Justice for Peace, a human rights organization in the southern city of Pattani.

On Feb 22, two soldiers were injured after a 5-kilogram (11- pound) bomb exploded near a market in Pattani, a common insurgent tactic. The bomb was detonated by remote control after soldiers earlier patrolled the area using GT200s and failed to detect the bomb, the Bangkok Post reported.

Thai courts don't admit GT200 readings as evidence in criminal cases. But the military has used them widely to identify suspects in the south who are then "invited" for questioning under emergency laws, says Sunai Pasuk, a Thai researcher for Human Rights Watch. The group has documented torture and other forms of abuse in military custody. …
