Exactly. Show this video to someone who has never seen it before and ask them to react in real time, narrating what they would do. They'd be like "ok he's reaching into his pocket, what, what is that? Is that a grenade? Oh shit!" and that's with their suspicions already up because you're showing them a crazy video.

Even people who are switched on, they're used to conflict that escalates. Almost no one is prepared to go 0 to 100 in half a second.
