A millionaire who sold fake bomb detectors to Iraq was jailed for 10 years yesterday after a judge said he had blood on his hands.
James McCormick (57) showed no reaction as he was told his "callous confidence trick" was the worst fraud imaginable.
At the Old Bailey, Judge Richard Hone told him: "I am wholly satisfied that your fraudulent conduct in selling so many useless devices for simply enormous profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent individuals."
He jailed McCormick, who was thought to have made £50m (€59m) from selling three models based on a novelty £13 (€15) golf ball finder to Iraq and other countries.
McCormick, of Langport, Somerset, was found guilty of fraud last week.
The prosecution said there was no scientific basis to the detectors.
Judge Hone told McCormick: "What you perpetrated was a callous confidence trick.
"The device was useless, the profit outrageous and your culpability as a fraudster has to be placed in the highest category."
He is believed to have sold 6,000 fake detectors to Iraq.
