To be fair, the cop told you to leave because he doesn't want to put you in danger. You mentioned he was confused and the intoxicated person was subdued (combative) and maybe he thought there was a gun. All signs of not wanting to put you (civilian) in danger.
I was successfully slowing traffic for my neighbors safety.
I never crossed the Fog line.
It was entertaining to watch the cops FU.
I was in the military for a few years,
although my AFSC was not Military
police, I got a lot of training from them
as I was classified as "world wide mobile",
and required to be "world wide mobile" all
the time. I kept a duffel bag/ sea bag in my car at
all times.
Of course cops think everybody are idiots.
They don't interact with the people that pay
their wages very much.
That is why cops are so dangerous.
