Can someone please explain Corliss testimony? SPOILERS
WARNING SPOILERS
There is something that I'm unable to wrap my head around. Here is my understanding: Haller needed Corliss to testify in order to get him to say that Roulet killed Renteria while the detectives happen to be in the court room (which is why Haller gave them subpoenas). But even with Corliss testifying that he heard Roulet bragging about the beating, the fact is Corliss is a documented liar, so how will that statement be used as future evidence if Haller wanted to have Martinez free and Roulet prosecuted for the murder of Renteria?
Furthermore (this is what I really don't get), how exactly did Haller set this up without Minton knowing that Corliss was a "jail house snitch" and wouldn't Minton refuse to put Corliss on the stand knowing Corliss was a liar?
Thanks
