ATLANTA (AP) – Police agencies across the U.S. are on edge and on guard after receiving threats and calls for violence against them on social media in the aftermath of the killings of two black men and the sniper attack that left five officers dead in Dallas. Some departments ordered officers to pair up or more generally said they were increasing security.
Authorities have said the Dallas gunman, who also wounded seven other officers and two civilians, wanted to “exterminate” whites. Since then, threats ranging from generic promises of violence to specific video postings have been made, heightening fears of further attacks.
In Dallas, authorities received an anonymous threat Saturday, prompting police to tighten security. Officers swarmed the department’s headquarters, searching for a reported suspicious person in a garage before issuing an all-clear.
