After a sleazebag mugs his grandpa, young Jamie has a chance to catch said sleazebag. He does several un-orthodox things in doing so, thus getting in trouble with the department, not to mention with Dad. It's one of those Catch-22 things where you think "yeah, he probably shouldn't have done that, BUT I WOULD HAVE DONE THE SAME THING! (Especially if it were MY Grandpa!!" I have seldom seen an episode of this show that I didn't like, but this one was outstanding.
