"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."
Meanwhile, Iraqis are still using his device at checkpoints across Baghdad.
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.'"
