Other mistake: In a number of episodes Mickey Bricks takes great pains to explain (usually to bent coppers) that he and his team are not thieves, making it plain that as a talented grifter he takes the high moral high ground over common criminals. The trouble is, he and every member of his team ARE thieves. In the very first episode "The Con Is On" Three Socks Morgan cleans out the bank accounts of a number of innocent people by rigging an automatic teller machine. He is stealing money, either from them or the bank. Stacie Monroe is shown picking pockets in a number of episodes and in "The Henderson Challenge" both Mickey and Danny Blue steal wallets from bystanders, a trick Mickey repeats in "The Return of the Prodigal." He also steals the victim's car. There are too many other examples to list here, but Mickey's pride in his exalted position as a master conman is definitely misplaced.
Plot hole: The team constantly has fake stories about them on news sites, so that when posing as businessmen/investors etc, the mark can look them up on the internet and find out more about them. Obviously, they have a few fake news sites of their own. The problem is persuading the mark that this is genuine. Many of their marks are bankers and businessmen, who would look for reports on legitimate financial/newspaper sites, rather than some random news site they had never heard of before.
