How could nearly 4,000 pounds of explosives have passed, undetected, into one of the city’s most tightly controlled areas ?
The first impulse was to look for infiltrators and collaborators. Some 60 suspects who had worked at checkpoints and local police posts near the bombings were rounded up. But the real problem, it turned out, was with the handheld bomb detectors being used at just about every Iraqi-run checkpoint in the country. They were toys. They had never worked. It had all been an expensive charade—costing the Iraqi government tens of millions of dollars and hundreds of lives—engineered by a portly middle-aged salesman in Britain.
