I know there will be plenty of conspiracy theories to flood in so I wanted to make a thread. I guess so far the theory is that it is another false flag and that there was more than one shooter, but I know this will change in time.
Saw this one pop up on my Facebook news feed already:
Seems to just be a misunderstanding of what the difference between a "Fort Hood Inspired" and an actual Fort Hood shooting is. This one can mostly be debunked by following the links in the videos description.
