I'll try to crop, enlarge, and repost the portion I'm talking about.
I think it was closer to the 2 minute mark. And if you look at the bright white area in the doorway, you'll see it on the bottom right of the bright area. That's a glass doorway leading to a warehouse area of the building. That area is sealed off from the rest o f the store and has no traffic, although at the time this was recorded there was no traffic anywhere since it was closed up and locked down.
