What's strange about it? The reporter is focused on the person she is interviewing, and the cameraman is concentrating on filming them.
The guy pulls out a gun and is about 1-2 inches away from them and no one sees as he points it directly at them? And if you look at 3:50, you can see her look at him, then turn back away to conduct the interview.
Even if someone was 6 inches away from me and pulled out a gun, my peripheral vision would still see the gun. The guy was RIGHT next to them.
As you know, I am 100% not a conspiracy theorist. But that is just strange. Dude is standing right next to them, hanging out, points a gun, and no one even notices him. Even if someone is walking up behind me, I can still sense then and I will usually turn around. Yet, this guy is there for like 45 seconds and not ONE person notices him, even after pointing a gun at them from 1-2 inches away? Sorry, that is ODD!!
