DARPA has been testing equipment that can detect chemical ingredients in weapons and explosives—before they’re used against us. And it’s almost ready to go.
The scene isn’t all that hard to imagine. It’s Memorial Day. The Indianapolis 500, the world’s largest sporting event, is underway. At least four-hundred thousand fans are standing, stomping and screaming. Far louder and more deafening, at 95 decibels, are the 550-700 horsepower engines of the thirty-three roaring Indy 500 twin-turbocharged race cars. Because the Federal Government considers this a National Special Security Event, the Secret Service, F.B.I., and FEMA are deployed alongside local and state police to keep everyone safe. Explosive-sniffing dogs, sharpshooters, security perimeters, license-plate camera scanners, and checkpoints are in full-force. But none of them notice the man parked nearby in a rented cargo van.
