[Eric begins tearing apart and trashing John's files]
John: How will you get your conviction without all this evidence, Eric?
Eric Matthews: I don't need this shit to convict you.
John: So go ahead. Destroy it.
Eric Matthews: I will.
John: Destroy it all. Just know it will not save your son if you do.
Eric Matthews: You kill my son, I kill you.
John: Go ahead. Why wait? We both know the sort of person you are, sir. The sort of person who guns down an unarmed suspect. In fact, the sort of person who plants evidence in order to obtain a conviction. The sort of person whose wife leaves him and his son hates him.
Eric Matthews: SHUT THE **** UP!!
