Sensors to Detect Chem, Bio Weapons in Chicago

Chicago is finalizing a contract for a security grid that would include sensors to detect chemical and biological weapons, the Chicago Sun-Times reported today (see GSN, Jan. 3).

The sensors are part of “Operation Virtual Shield,” a plan to link some 2,250 cameras and equip them with software capable of spotting “suspicious and unusual behavior,” according to the Sun-Times (Fran Spielman, Chicago Sun-Times, Jan. 31).
