Actually, I went back and listened to the video. At about the 3:11 mark in the video you can hear the first shot. At about the 3:17 mark you hear a second shot and and at 3:20 a third shot. At about 3:27 the person recording the video pans the camera and at about 3:37 you can see the crowd begin rushing for the exits.
At 3:45 someone asks what's going on. At about 3:50 the first long burst of full auto fire is heard. So, actually, the crowd disperal was well underway by the time of the first long burst.
I wonder what possible explanations exist for the initial single shots?
“I wonder what possible explanations exist for the initial single shots?”
No need to wonder, just make something up!
I keed, I keed, though many are certainly coming up with, um, ‘creative’ theories.
