Did You Know?


This story is based upon a real incident. After the Shah of Iran entered the USA for medical treatment, Iranian "students" took over the American embassy in Tehran and held the American's there hostage. This happened two months before this episode was originally broadcast. See more »


The security and a criminal investigation is done by Customs Agent Niven. He also performs the duties of a State Dept diplomat. None of these are a Customs duty. The security would have been handled by either the Diplomatic Security Service of the State Dept. or the Secret Service. The investigation would have been handled by either of those or the FBI. And there would have been a true State Dept. representative there. Niven only does it because he was on a prior show, as well as a few subsequent ones. (For some reason in this one episode his character's name is changed to Devon). See more »

Murder episode with gaping plot holes
24 October 2015 | by See all my reviews

Diplomatic Immunity begins with the President of a Latin American country (Rudy Solari) being admitted to a Los Angeles hospital for a critical operation amidst protests and an assassin stalking him. Despite tight security around him, his Vice President is killed and representatives from the State Department ask Quincy (Jack Klugman) to conduct the autopsy. When Quincy has difficulty getting a continuance from an unsympathetic judge in the trial he is already scheduled to testify in, he must work remotely coordinating with Sam (Robert Ito) and Dr. Asten (John S. Ragin) in the coroner lab to determine the cause of death and help prevent an assassination.

I found the first half of this episode to be pretty dull but then things picked up after that, too bad it wasn't enough to make up for the gaping plot holes. First of all, if the security was so tight in the hospital with the federal and local government hovering, how did an unauthorized person with a fake employee ID get in there and so close to the Latin president and his staff with no one realizing? They would have done background checks on every employee working on that floor in a situation like this, so that was ridiculous. I also didn't understand why the killer first took out two members of the presidential staff raising the awareness of everyone and creating further scrutiny rather than just taking out the intended target? Maybe this was a mistake, but since it is all done off screen we have no idea. All of this coupled with a local judge defying a State Department directive to postpone a trial for a couple of days on a matter of international security was just absurd and made it difficult for me to take this story seriously.

Although there is a murder featured in this episode, there is very little mystery as we know right from the beginning who is responsible. Definitely not a good Season 5 episode, especially from a quality standpoint.
