Not to diminish the size of this fine officer's balls in any way... But i get the feeling he was more dedicated to not getting run over by a speeding bus than his duties in the moment..
A taxi I was in in Vietnam ran over a guy on a motorbike, and the driver ran out real quick to see how he was before gunning it to get away from the police that were approaching. I think people generally don't like to deal with the police in Vietnam, and this video and the rampant corruption is why.
