I saw the video that the shooter posted, very horrific, but not bloody since he ended up putting the camera in his pocket so he could use two hands while he committed double murder and attempted to kill the 3rd person (the lady who was being interviewed).
The video is harrowing though, he walks up to them and no one notices, he points the gun at the young woman and whispers "bitch" and no one notices, then he starts popping off shots and missing, that is when the camera gets put away and you here him firing many more shots, which I assume were the fatal ones. Very sad.
