[en] in France, police are shooting DNA marking spray during demonstrations. They call it PMC, produit de marquage codé. Possibly invented in 2004 by a British company, DNA marking spray is commonly installed as a shower over a door, accompanied by video surveillance, to dissuade theft in shops. It's relatively commonly seen in Amsterdam, signs announce the use. The new thing is that the French police is disseminating the spray using specifically engineered guns. #pmc #dnaspray #riotpolice
