I enjoy watching "Quincy" but will also be among the first to admit that the plots were not always 100% logical. Well, so's the case with "Diplomatic Immunity"--an entertaining but flawed show.
The program begins with the dictator of some fictional South American nation coming to the US for medical treatment. Not surprisingly, the State Department insists on tight security, as practically everyone wants this jerk dead. Oddly, however, folks in his party start dying--but not him....yet. And, because the show is called "Quincy", the US government wants Quince to do the autopsies to get to the bottom of it. The problem is that Quincy has also been subpoenaed to testify in a criminal case--and the hard as nails judge won't let him out of the trial. So, it's up to Sam and Asten to work on the case and to keep Quincy advised through periodic phone calls and after hours visits.
Logically speaking, it's hard to imagine a judge in a criminal trial not postponing the trial, a bit, to accommodate the State Department. Also, logically speaking, it's hard to imagine that there is no other coroner in the entire United States who cannot handle this case!! And, now that I think about it, the was the folks were murdered is incredibly far-fetched. Yet, oddly, the show is compelling viewing. A slightly poorer than average episode.
