In S1E8 Ruby finds out at Stan's work place that Eddie is helping the police. This definitely looks like the reason for Rio's arrest and not robbery. In S1E10 we see Beth watching news on TV that Rio has been arrested. In S2E1 agent Turner says to Beth, "picture my damn face when I see that you were the hostage in the very robbery that took down the gangbanger". So he is implying that the robbery caused the arrest of the gangbanger (Rio). Is this fact correct? How did robbery cause the arrest of Rio? Rio wasn't anywhere in the act of the robbery.
