A CONFIDENTIAL, 120-PAGE catalogue of spy equipment, originating from British defence firm Cobham and circulated to U.S. law enforcement, touts gear that can intercept wireless calls and text messages, locate people via their mobile phones, and jam cellular communications in a particular area.

The catalogue was obtained by The Intercept as part of a large trove of documents originating within the Florida Department of Law Enforcement, where spokesperson Molly Best confirmed Cobham wares have been purchased but did not provide further information. The document provides a rare look at the wide range of electronic surveillance tactics used by police and militaries in the U.S. and abroad, offering equipment ranging from black boxes that can monitor an entire town's cellular signals to microphones hidden in lighters and cameras hidden in trashcans. Markings date it to 2014.

Cobham, recently cited among several major British firms exporting surveillance technology to oppressive regimes, has counted police in the United States among its clients, Cobham spokesperson Greg Caires confirmed. The company spun off its "Tactical Communications and Surveillance" business into "Domo Tactical Communications" earlier this year, selling the entity to another company and presumably shifting many of those clients into it. Caires declined to comment further on the catalogue obtained by The Intercept or confirm its authenticity, but said it "looked authentic" to him.

"By design, these devices are indiscriminate and operate across a wide area where many people may be present," said Richard Tynan, a technologist at Privacy International, of the gear in the Cobham catalogue. Such "indiscriminate surveillance systems that are not targeted in any way based on prior suspicion" are "the essence of mass surveillance," he added.
