An Italian artist has declared a ‘brush-and-ink’ war on mass surveillance – he looks for private photos of high-ranking US intelligence officials, reworking them in a stencil technique. He then posts them on walls in capital cities across the globe.

Turin-based conceptual artist, Paolo Cirio, is targeting key figures “in scandals regarding secret intelligence operations, statements, and policies on bulk collection of private communications,” in his anti-spying campaign dubbed “Overexposed.”

In order to ‘overexpose’ the top spies, Cirio was looking for “unauthorized” photos: “from selfies, to family celebrations, to other intimate situations”.

“Seeking photographs of governmental officials is a form of creative espionage that was conducted with hacks on social media, social engineering, and simply with search engines,” the artist told RT.

The intimate photos uncovered of NSA and CIA officials would then “appear as posters and murals” in New York City, London, Berlin and Paris.

The artwork targeted four National Security Agency (NSA) officials: the current NSA chief Michael Rogers and former heads of the agency Michael Hayden, James Clapper, as well as Keith Alexander, who resigned shortly after the Snowden revelations.

The Central Intelligence Agency (CIA) also came under the spotlight of the democracy-oriented artist. Portraits of John Brennan, the current agency director, its ex-chief David Petraeus and former deputy director Avril Haines have been emblazoned on the streets.

Cirio also dealt with James Comey, Federal Bureau of Investigation (FBI) director and Caitlin Hayden, former National Security Council (NSC) spokesman.

The artist says he chose this form of street art for his revenge campaign “because that is where people can see these pictures more often and they share them on social media, so these politicians get even more exposed.

“People understand what they are and what is their accountability on mass surveillance,” Cirio said, “My personal concern is these people are like physically spying on everyone worldwide.”
