slow motion hero

Stopping for beer and cigarettes at the Quick Stop on 79th Ave in N Phoenix, already a little jagged, we see 5 of the City's finest. Just hanging out, drinking free sodas. I freak. My friend doesn't.
I ask, whispering, "should we just get out of here?"
He says no.
What then? I ask.
He says "can't make a sound, can't make a sound".
We didn't. They didn't even notice. We got beer and cigarettes.
Back outside, my buddy explained that's slow motion, they don't Tase you unless your too quick.
I really don't know what that means but it worked.
