It is believed the man seen in this video is the las vegas shooter, Stephen Paddock, attending an anti-trump protest in Reno Nevada in August 2017.
***Update @ 1:30 EST. Media just released the shooter was a former employee of Lockheed martin, a company that has exclusive contracts with Nasa, that’d explain the Nasa shirt in the video. (thanks to Mark)
Not surprising. Pussyhat and all.
