So this 64 year old was not only shooting up the concert, but was monitoring hallways and picking off security guards?
Yea, sure, all at the same time over the 45 minute period when the shooting at the concert only lasted for 10-15 minutes recorded on all of the cell phone videos. I counted three periods of automatic fire. Some say there was a fourth but I have yet to correlate that to be a fact.
I suppose you are not aware enough of the relatively new cameras that connect directly to a cell phone app. We do know the cameras were placed, what we don’t know is what he used to monitor them. BTW, the app also alerts the user when there is IR movement.
Pull your head out.
