Hey now. No need to be sensible.
The cop was over-zealous. But when he got rushed, he was within his authority to pull his gun. He was surrounded by half a dozen people, with two males coming towards him. What in the fuck gave them the idea to think that was okay to do?
When the cops give you an opportunity to leave, you fucking leave. Get in your car and drive away, walk away, get on your bike, catch a sky-hook ride from the CIA. Whatever. What you do't do is stick around, scream, and rush at them.
Yeah. He is guilty of being overzealous.
