She is perfectly describing the school-shooter actor(s) costume used in one or more live-fire drills at Florida schools prior to this one. I have a video with the footage of one of these drills where the shooter in the drill shooting blanks matches her description of the Parkland shooter to a T. Add that teachers & students alike were expecting one of these realistic active shooter drills with blanks being fired, and it really seems and looks and sounds like a drill. The official story is definitely a lie, whatever happened!
