ATLANTA — Attorneys from Hall County argued Monday before the Supreme Court of Georgia regarding an alleged terroristic threat referencing Columbine posted in 2014 on Facebook by a former Lanier Charter Career Academy student. Devon Major was charged with terroristic threats after a post to get “the chopper out and make Columbine look childish.” A chopper is slang for a gun, and the 1999 Columbine shootings in Littleton, Colo., killed 13 people.
