Transcription: Forensic Architecture

Triple Chaser, 2019

Narrator: On November 25, 2018, U.S. agents fired tear gas at migrants, on the Tijuana-San Diego border. The tear gas was manufactured by the Safariland group, owned by Warren B. Kanders, the Vice-Chair of the Board of Trustees of the Whitney Museum of American Art, which commissioned this work. In response, Forensic Architecture is training a machine learning classifier to search for images of tear gas grenades manufactured by the Safariland group. We took as our test case the Triple Chaser tear gas grenade, manufactured by Defense Technology, a subsidiary of Safariland. Computer vision using machine learning begins by training a classifier to recognize objects in images. Bounding boxes and masks tell the classifier where in the image the tear gas grenade exists.

[Pause]

Narrator: This process usually requires a training set of thousands of images. But we were only able to identify fewer than a hundred images of the Triple Chaser online. So, we set out to create a synthetic training set. 

[Rustling of a knife against leaves]

Narrator: We reached out to activists to find and photograph Triple Chaser grenades. An insurance claims adjuster named Mikol sent us this video from Tijuana. [The sound of birds in the distance] And artist Emily Jacir sent us this from her Bethlehem art and research center, probably the most tear-gassed artist residency in the world. 

[Pause]

Narrator: From these we created a digital model, according to the specifications in the product catalog. [Pause] We recreated all the permutations of Triple Chaser branding around the world. [Pause] And using this model, we generated thousands images.

[Long pause]

Narrator: We set the model against bold patterned backgrounds to ensure that the classifier learns to identify the grenades, rather than the common elements of the backgrounds in which they often appear. We used colored masks to tell the classifier where the grenades are in the image. We also placed the model in photo realistic environments. 

[Pause]

Narrator: In 2016, Warren B. Kanders gave 2.5 million dollars to the Aspen Music Festival. In thanks, the festival renamed the Sunday concert series in his honor, the inaugural evening of which began with a performance of the Four Last Songs by Richard Strauss. 

[The Four Last Songs by Richard Strauss plays, operatic singing layered under the narrator's speaking]

Narrator: Now that we have created a synthetic data set, we trained the machine learning algorithm to recognize Safariland Triple Chaser tear-gas grenades. [Operatic singing] These images are sampled from our synthetic training data set. 

[Operatic singing, full orchestra]

Narrator: We also trained the classifier to recognize what is not a Triple Chaser grenade. And we trained it to recognize the Triple Chaser in simulated real-world environments. 

[Operatic singing, full orchestra]

Narrator: Safariland safety guidance provides the following information to doctors: Severe allergic skin reaction, bronchial spasms, and anaphylactic shock are possible. Irritant to eyes. Irritant to skin and mucus membranes. Breathing difficulty. Disorientation. Danger. Danger of blast or crush-type injuries. Danger of pulmonary edema. Danger of disturbed cardiac rhythm. Danger of convulsion. Danger of impaired breathing. Danger of cerebral edema.

[Silence transitions into the sounds of tear gas and bullets being fired at a Turkish protest, intermittent yelling, coughing, and screaming]

Narrator: Several members of our team have experienced the effects of tear gas. One was amongst the Turkish citizens who protested in Gezi Park, in 2013. During the nation-wide protest that followed, Turkish police fired 130,000 tear gas grenades. [People yelling, a woman sobbing] While tear gas is banned from use in war, governments use it to suppress the right of civilians to collectively protest in public space. Safariland sells tear gas grenades around the world. We have found evidence of its use against civilians in the U.S., Turkey, Peru, Iraq, Israel-Palestine, Yemen, Bahrain, Tunisia, Guyana, Venezuela, Egypt, and Canada.

[Silence]

Narrator: After we train our classifier on synthetic images, we will deploy it to search for real ones, leveraging tags and key words. [Pause] The system returns a percentage for each image, indicating its confidence that the highlighted pixels signify a Triple Chaser tear gas grenade manufactured by the Safariland group. 

[Pause]

Narrator: In 2017, the Claris Corporation, of which Kanders is Executive Chairman, purchased the U.S. manufacturer Sierra Bullets for 79 million dollars. As part of our investigation, we discovered that Sierra's Open Tip MatchKing bullets, seen here, are used by Israeli Military Industries, or IMI, the preferred supplier of ammunition to the Israeli army. [Pause] We worked with activists to gather cartridges on the Israeli side of the Gaza border. What they found shows that the Israeli army fired IMI ammunition into occupied Gaza. Between March and December 2018, Israeli snipers killed 154 civilian protesters on the Palestinian side of this border fence, including thirty-five children. More than 6,000 were wounded. A member of our team was at the protests in Gaza, and gathered this footage with local filmmakers. 

[Sounds of faint yelling, gunshot as a man is shot in the leg, louder yelling as others gather around him to assist him and document the incident]

Narrator: The U.N. concluded that the actions of Israeli soldiers during that time may constitute war crimes, or crimes against humanity.

[Screaming of victimized man. Silence]

Narrator: We contacted Sierra to ask if their bullets are used by the Israeli army.

Sierra Representative: [Through phone speaker] Are you still there with me, sir?

Man: Yes, sure.

Sierra Representative: Okay. As far as how our product is being used by other companies, I'm told that it's confidential, and it's not information that I can give out.

Narrator: We shared our findings with the European Center for Constitutional and Human Rights, who served Sierra Bullets with legal notice, warning that the exports of their bullets to Israel may be aiding and abetting war crimes.
