How has the threat of terrorism impacted residents of urban spaces in the 21st century? This documentary explores how cameras, computers, and data technology are evolving to serve as watchful guardians (or, as some would say, intrusive monitors) of the world's bustling cities. Probing questions about rights to privacy and access to information are reviewed at a time when the long shadow of the September 11 attacks continues to darken─or illuminate─the debate. 52 min. Widescreen; Soundtrack: English.
