Authorities in Antioch, a city grappling with ongoing racial tensions, have launched an investigation after a social media post called for “hangings in town square” to “fix Antioch right up.” The post, which surfaced just a year after Antioch’s police department was embroiled in a scandal involving officers exchanging racist and homophobic messages, has intensified concerns about hate speech and violence in the community. Interim Police Chief Brian Addington confirmed this week that the post is being investigated as a potential criminal or terrorist threat, but declined to provide further details, saying the inquiry should be completed in the coming weeks.
