So, yeah, he did nothing. If he "secured the perimeter" how did the perp leave the premises?
Said by Scott Israel, who was not there, saw a video, but did not and has not heard the audio transcripts by his own words. Also, if you look at the floor plan of Bldg 12, he cannot be in the stairwell unless he is inside bldg 12. Some contend he was in another building across from it, but I have heard two other YouTube statements saying they saw him IN Bldg 12, but then exited. I wonder why?
