There's No Place Like Home - S2-E1
Factual error: This is at the end of the episode, when Jordan takes the key that she found for the 66 Ford and tries it in the ignition it should have been a square key. Round keys were for the doors and trunk. Back then they made two keys - one that opened the car doors and trunk and one that started the ignition. She never even tried the key in the trunk.
Answer: It would best to cite a specific episode; however, a dismissal is not the same thing as a mistrial by legal definitions. A case may be dismissed with or without prejudice. A case dismissed with prejudice would prevent a retrial on the grounds of double jeopardy. When this happens, the judge is basically saying he or she has heard enough to make a final decision and the case is over. Dismissals without prejudice and mistrials that the defendant consents to can be retried (generally it's the defendant's lawyer that will move for a mistrial for one reason or another).
