“It's like asking, what's an impostor look like?" Arctor said. "I talked one time to a big hash dealer who'd been busted with ten pounds of hash in his possession. I asked him what the nark who busted him looked like. You know, the -- what do they call them? -- buying agent that came out and posed as a friend of a friend and got him to sell him some hash."

"Looked," Barris said, winding string, "just like us."

"More so," Arctor said. "The hash-dealer dude -- he'd already been sentenced and was going in the following day -- he told me, 'They have longer hair than we do.' So I guess the moral of that is, Stay away from guys looking the same as us.”
