Halloran is a prospective informant against Bulger who's murdered after Connolly leaks his identity to crime boss. Shady. By now, the rest of the FBI has no illusions: the deal with Bulger is causing more evil than it's stopping.

The assassination of Roger Wheeler is Bulger's boldest move ever. He's killed plenty of people already, but none were as prominent or as well-connected as Wheeler. It just goes to show how powerful this project-born ex-con has become.

As time rolls on, Connolly and Morris become a well-oiled cover-up machine, successfully derailing any investigation into Bulger's violent crimes. This only makes Whitey more confident, culminating in his assassination of an Arizonan multimillionaire for screwing up a business deal.
