At 4:20 one of them says, "We had a guy shooting" even though clearly no one is shooting at the time. What's up with that?
It's not clear that no one is shooting, though. It's only clear that the available and very limited perspective did not capture such activity.
02:15 No hold on. Lets come around. Behind buildings right now from our point of view. ... Okay, we're gonna come around.
02:19 Hotel Two-Six; have eyes on individual with RPG. Getting ready to fire. We won't...
02:23 Yeah, we had a guy shoot---and now he's behind the building.
02:26 God damn it.
02:28 Uh, negative, he was, uh, right in front of the Brad Uh, 'bout, there, one o'clock.
02:34 Haven't seen anything since then.
