I have been saying it for days, don't assume the video we have been shown is from the actual shooting, that is what were are told to believe happned. Did you notice the arrested person of interest does not look at all like our shooter in the video? Why did they cover his face?

One fake video, with a narrative.
One separate real event with multiple (professional) shooters (eyewitness claimed two shooters at second mosque) One patsy to take the fall (probably under mind control or drugs)
