No evidence, just a gut feeling. Maybe he was part of a protection racket for the drug lords. Like the redemption of Han solo in the star wars. I do not think an insurance salesman would hrmph (useless) so sarcastically if someone (Pippin) said they were a sales man.
I am not sure if he said "a salesman" or "ah, salesman". When he is met with the same treatment as he gave Pippin, he sure was quick to say he did other things too.
On an aside Rose McGowan is sooo hot and my stomach is much weaker than it was. The blood and wound special effects make me Ill. I guess I will not worry about missing something while reading this site.lol
