In the course of doing its business in selling and maintaining its Cryptophone 500 phones — secure mobile phones for clients who need and can afford military-grade security — ESD America said it has randomly discovered the existence of at least 18 interceptor cells in the D.C. area. Fifteen are in downtown Washington, including several very near the Senate and the White House, plus another three in northern Virginia. CEO Les Goldsmith said, “It’s highly unlikely that federal law enforcement would be using mobile interceptors near the Senate.”

“My suspicion,” he said, “is that it is a foreign entity.”
