Three years ago, I challenged DHS scientists to find a way to produce cheap ($150) forensic cameras that would survive a terrorist blast. It took way longer than I expected, but tests at Aberdeen recently show that the cameras do work. This means that standalone (and therefore privacy protective, since the film is only inspected after an incident) cameras can be cheap and nearly blast proof. This could change things for mass transit security in a big way.
"There wasn't much left of the bus except the wheels and chassis. But the cameras survived, and that was the point."
Did the cameras' memory chips survive the blast intact? Fourteen out of 16 did.
