‘Tear Gas Tuesday’ in Downtown Portland (Oregon)
Forensic Architecture (FA) at Goldsmiths, University of London
Despite being broadly banned in warfare under the terms of the 1925 Geneva Protocol, tear gas as an agent for so-called ‘riot control’ has become the preferred means for police, in the US and around the world, to clear dissenting voices from public spaces. But the toxic chemicals contained in tear gas and other widely-used chemical munitions can cause serious short- and long-term side effects, from asthma and chemical burns to lung injury and neurodegeneration.
