Meme-obsessed gunman killed after opening fire in Dallas courtroom

22-year-old Brian Isaack Clyde reportedly opened fire in Dallas's federal courthouse today and was killed by cops shortly thereafter.
From his Facebook feed, a few months ago: a photo of a man posing with a rifle in medieval armor, his anime waifu bodypillow nestled in one arm.

An initial search of public records did not uncover a criminal history.
