Duncan Lemp, a 21-year-old Maryland man was shot to death in a predawn raid in March 2021 after police smashed in his bedroom window and tossed flash bang grenades into his bedroom. Lemp was active on Twitter and liked several tweets by Libertarian presidential candidate John McAfee. Lemp’s last tweet declared: "The Constitution is dead." Two months later, so was Lemp.
The Maryland government later admitted that Lemp was targeted in part because was "anti-government" and "anti-police". Plus, Lemp was outspoken about his support of the Second Amendment and posted photos of himself with guns on Instagram. Police saw one such photo and concluded that Lemp possessed a semi-automatic rifle that was illegal to own in Maryland. After they killed him and searched the Lemp home, they realized they had mis-identified the firearm—it was legal. But police, prosecutors, and local politicians treated that like a harmless paperwork error: nobody cared about the wrongful killing of Duncan Lemp.
