That video is also incomplete. That little adventure had a very satisfying ending.
The brass-balls guy not only successfully out-drove the robbers by bashing up and wrecking their vehicles, he fargin incapacitated them, then parked and took the gun from the useless, frozen guard guy, got out and went hunting the robbers. <--TINS
What you see there is what you will see in the grass. There will be some who totally wide-eyed freeze into what is essentially a catatonic state like that passenger (I cannot call him a guard). There will be others that stay with the situation, hold their fears behind them while they tend to their own attack.
Notice the guy driving even has time to instruct the frozen dude to load his weapon. And ignores the useless twit's inability to keep the rifle out of the driver's face.
