Well, perhaps. It might be true that he was tempted by access to a whole pile of money, and regretted it. It's a fairly normal human reaction. It's not much of a defence though, especially from someone in law enforcement.
OTOH, what Carl Force is accused of is a whole other level of wrong and if proved, deserves serious time.
