Expert Witness

Katz is called to testify as an expert witness in the trial of a boy named Roger who broke into an elderly couple's home, tied them up, then wrote with permanent markers all over their walls. The issue is whether he's mentally competent to stand trial, and it's up to Katz to determine that. Ben wants to know why Katz is doing this, instead of the ""charlatans"" they usually get (""They were busy,"" Katz says), but when he learns that it pays $400 an hour, he encourages this new pursuit of his dad's. Eventually, Katz finds Roger not competent to stand trial.
