You put your hands behind your head and say aloud, “I give up!” 
“What? Hello?” says a voice from between the trees.  “Who’s there?”
Walking toward the voice, you say “I surrender; I’m tired of running.”  As you say this, you nearly trip and fall onto the cop, but manage to catch yourself as you realize your hands aren’t actually bound.
“Um, why are you surrendering?” the cop is tall and very dark skinned.  Definitely not one of the ones you met at the station earlier.  “I’m just making sure you’re alright.  You looked pretty scared when you ran past my car.  Who’s chasing you?”  It looks like he really doesn’t know.
