What's random about it? From the chatter, there's a ground force element moving in that direction. The pilots see a group of men gathered in the street, some of them undeniably carrying weapons. They see a man with a long tube crouching around a corner and pointing it down the street. There's a line "Yeah we had a guy shooting", indicating that fire had already come from this group, or at least the pilots thought it had. There's nothing random about it. They may have been wrong, but it wasn't random targeting of people walking around town. The van portion of the incident is more questionable. It sounds like they followed the rules they had, but those rules may not have been proper for this situation.
