Perhaps the teacher is the patsy?
Earlier reports said the teacher that propped it open was killed.
Early reports said the shooter was ‘engaged’ by officers before he entered... then they said he wasn’t.
What are those two men in black standing about 100 feet from the perp and the door doing?
Pause on the first second of this video.
Who are those two guys to the left of the frame?
Why are they letting a guy carrying a long rifle masked up in all black enter a school?
How - of all places - did the shooter know to go to that specific door?
