This has been the most confusing fact to establish. Did he, or did he not use a Bushmaster AR? If not, as purported by NBC here, then the MSM has deliberately suppressed this information for political purposes.
The media claimed a Bushmaster AR was found in a car in the parking lot but if you watch the video, it appears to actually be a shotgun.
Part of the confusion (besides the media rushing to be first with the story and not fact checking) is when the corner said something along the lines of they were shot with the ‘big gun’ people assumed she meant rifles. However, anyone here knows that the diameter of a .223 round is actually quite small and if he had a .45 pistol, that could have easily been considered the ‘big one’.
