@crimexpod: The spray wasn’t just meant to stop the crowd—it was designed to leave a mark. During the 1980s, some law enforcement agencies used a crowd-control spray called Dye Witness. It looked much like conventional pepper spray, but its dark green foam contained a powerful marking dye. Once sprayed, the dye could cling to a person’s skin and clothing, making them identifiable even after the crowd had scattered. And the stain? Not exactly easy to wash away. For authorities, it served two purposes: dispersing crowds and helping identify individuals afterward. For anyone caught in the spray, the evidence could literally follow them home. A strange—and largely forgotten—piece of crowd-control history. #History #PoliceHistory #1980s #InterestingFacts #ForgottenHistory Source: @historynows
