The devices were also sold to Pakistan and have been used outside of major American hotel chains in Karachi, as witnessed by this reporter.
"We will now pursue McCormick's wealth," Rock said, "and make sure crime does not pay."
Iraqi General Jihad al-Jabiri, who used to lead the Baghdad bomb squad and helped McCormick win his contract, is now serving a jail term for corruption.
Reporters cornered McCormick outside the courtroom. Asked how he could continue to defend his product, he said simply, "I'm still defending it. I still am."

As part of the BBC investigation, a whistleblower described how he walked away from the company after confronting McCormick.
"I said, 'If this really doesn't work, I can't be any part of it,'" the whistleblower told the BBC. "He said, 'It does exactly what it's designed to.' I expected him to say detect explosives, ivory, gold. He never said that. He said, 'It makes money.'"
