The Victim - S4-E17
Question: During the trial, Matlock says that he paid a man to follow Bret which is how they were able to find the rope that Bret used. Would what Ben did to prove that Bret was the killer actually be allowed?
Answer: I did not see this episode, but YES. Both prosecution and defense lawyers use investigators to search for and uncover evidence that is legally admissible.
