In The Lincoln Lawyer, the state prosecutor (Ted Minton) puts a prison cell snitch ("DJ" Corliss) on the witness stand to testify about what the main antagonist (Louis Roulet) allegedly told him when they were in a lockup:
The main protagonist — the "Lincoln" lawyer (Mickey Haller) had actually asked Corliss (through Gloria, one of his clients, who was serving time at a drug rehab with Corliss) to cooperate with Minton:
Haller apparently did that to kill 2 birds with one stone:
- To win the current case against Roulet (his client) — charge of assault of Regina Campo — by showing that Corliss actually lied in the past about his cellmates; and
- To get Roulet charged for killing Donna Rentiera — about which Roulet himself had confessed to Haller (talking advantage of the client-attorney privilege). Haller wanted this because the murder of Rentiera was his old case in which an innocent man got life in jail (Jesus Martinez) — in whose innocence Haller did not believe back then.
Roulet now claims that Haller had actually set Corliss up to testify about Roulet's murder of Rentiera, to which Haller reasonably responds "How?".
He questions Haller: "I wanna know how Corliss got that shit he's saying":
That questioning does not make any sense to me. Roulet must have told Corliss about it himself in the lockup. If he did not, how else could Corliss know the details?
It would be understandable if Haller had actually secretly talked to Corliss and gave him the details of Rentiera's murder. But I do not see any indication that this happens.
So, does Corliss lie or not about Roulet's bragging? If not, why does Roulet question Haller how Corliss knows about it?
