If the cop walked 50 yards from his vehicle, I'm thinking he was 'set up'. A 50 yard walk away from your vehicle with 3 suspicious dudes lurking about in a remote wooded/marshy area is NOT a wise maneuver before backup arrives.
I should also mention the possibility this could be a terrorist ambush of the Islamo kind. Perhaps the two ‘whites’ are really Muzzies?
Yes, the time frame is very tight. I was surprised when I read it.
Ends up nothing like that - the cop lied.
