"The defendant, while continuing to shout 'Do something!'" shoved Micah Fletcher in the chest," the affidavit says. "The video showed the defendant appear to pull a folded knife out of his pocket and conceal it in his hand. Micah Fletcher is then seen shoving the defendant, who stumbled and the defendant continued to conceal the knife in his right hand. The defendant stood and spoke to Micah Fletcher, says 'Hit me again,' while Micah Fletcher continue to tell the defendant to get off the MAX."
