Visible crew/equipment: Jessica is at the crime scene with the detective and walks from the back of the set to the cemetery. The moving shadow of the camera is cast on a rocky wall. (00:17:33)
Visible crew/equipment: When the cop grabs the coffee pot, a filming crew member with blue trousers is reflected on it.
Who Killed J.B. Fletcher? - S7-E14
Factual error: Bremerton, Washington is not a hick town as depicted in this episode (it is the home of Puget Sound Naval Shipyard, a US Navy installation that employs 14,000 people) and the people there do not have southern accents.
Dead Letter - S6-E6
Factual error: Unlike the Connie Kowalski character in this episode, real insurance investigators are not trained in arson investigation. Insurance investigators search for evidence of fraud relating to insurance claims. Arson investigators are professional firefighters who have had extensive additional training in arson investigation.
Fire Burn, Cauldron Bubble - S5-E13
Factual error: The only instances of "witchcraft" or "witch trials" in America were in Salem, Massachusetts. There were none in Maine or anywhere else. The Salem witch trials spanned 15 months, from February, 1692 to May 1693. Over 200 people were accused of witchcraft, but only 30 were found guilty. Of the 30, 14 women and 5 men were executed by hanging and one man, Giles Corey, was executed by "pressing." Another five died in jail, but none were burned at the stake, which was a punishment unique to Europe.
Factual error: When Buck's body is found, his blood is red when it should be brown due to oxidation after how much time has passed.
Visible crew/equipment: When the sheriff and the mayor meet at the fix-it shop, the filming crew plus the boom mic pole are reflected on the side of the red car.
Plot hole: Buccaneer was created by Mr. Vandervelt, so Mr Kimble would never be able to use it to race under any circumstances. (00:42:45)
Funeral at Fifty-Mile - S1-E22
Other mistake: It's a clear day not a stormy night as it should be when showing the barn in the flashback. Look closely and you can see a clear sky through the barn walls cracks.
Continuity mistake: When Danny dives into the ocean he's wearing different shorts than he was on the beach.
Plot hole: There were 3 gunshots. 1 from Magnum, 1 from the killer and 1 from the victim. Yet they arrest Magnum with checking the bullet striations. He would be declared innocent almost immediately. (00:17:00)
Plot hole: Barney Kale decides to reopen a case he couldn't solve. Based on the outcome it makes no logic whatsoever. He is the murderer. Why would he bring attention to it put himself in danger? (00:46:50)
Suggested correction: He was being blackmailed by Gary Roberts. He "reopened" the case as a ruse to kill Roberts.
