Army warns soldiers about copycat shootings at 'Joker' screeningsGizmodo obtained the memorandum that was circulated by the military about "incel" extremists wanting to replicate the 2012 Aurora, Colo. mass shooting when a gunman killed 12 people and injured 70 during a screening of The Dark Knight Rises.
"Incels are individuals who express frustration from perceived disadvantages to starting intimate relationships. Incel extremists idolize violent individuals like the Aurora movie theater shooter," the document read. "They also idolize the Joker character, the violent clown from the Batman series, admiring his depiction as a man who must pretend to be happy, but eventually fights back against his bullies.
"When entering theaters, identify two escape routes, remain aware of your surroundings, and remember the phrase 'run, hide, fight,'" it continued. "Run if you can. If you’re stuck, hide (also referred to as “sheltering in place”), and stay quiet. If a shooter finds you, fight with whatever you can."
