The FBI reported the fraud in 1996, but the scam was brought to the U.K. under a different name. It was eventually dubbed the ADE-651 and sold to Iraq, Niger and Saudi Arabia, among others.
In 2013, British conman James McCormick was given a 10-year prison sentence over the ADE-651. He made tens of millions of dollars selling the device to Iraq's government, yet Iraqi checkpoints have continued to use that useless equipment.
A police officer in Baghdad told The Washington Post on Monday morning: "We know it doesn't work, everybody knows it doesn't work and the man who made it is in prison now. But I don't have any other choice."
When the prime minister visited the scenes of the bombings Sunday, people threw rocks at his convoy and called him a thief.
