Other mistake: If the cartel's money to be cleaned is from selling drugs then why is it all brand spanking new? In season one he gets it delivered in a van in boxes. When they open them the money is new bills, still in bank wrappers. Why would people buying drugs go to the trouble to going to the bank to get new bills?
Other mistake: Marty tells Ruth he'll pay her $1000 a week when he asks her to run the strip club. Later in the season, Ruth has demands, and says she wants to make 25k a year. Marty says "done." $1000 per week would have been $52k a year.
