- At 9 p.m., Nagel, the Secret Service's assistant director for investigations, issued the "go" order. Agents armed with Sig-Sauer 229 pistols and MP5 semi-automatic machine guns swooped in, aided by local cops and international police. The adrenaline was pumping, in part, because several ShadowCrew members were known to own weapons. Twenty-eight members were arrested, most still at their computers. The alleged ringleaders went quietly, but one suspect jumped out a second-story window. Agents nabbed him on the ground. Later, they found a loaded assault rifle in his apartment. The operation was swift and bloodless. "[Cybergangs] always thought they operated with anonymity," says Nagel, a tall, chiseled G-man. "We rattled them."
