After Garcia goes outside to get her satellite phone system working, she hears a suspicious noise and goes to investigate. The scene shows her walking alongside a camp trailer. The next camera cut shows still approaching the same camp trailer. Obviously, the two shots are reversed.
The BAU is called in to assist the Sheriff's Dept. in Franklin, Alaska (a made-up town, although there is a ghost town by that name). By statute, Alaska has never had any Sheriffs. Functions filled by sheriffs elsewhere fall mostly under the auspices of the Alaska State Troopers. Other law enforcement is by community or (rarely) borough which is what Alaska has instead of counties.
There are many night scenes and even references to "starting fresh in the morning". This takes place in rural Alaska, based on the weather, the amount of snow on the ground & lack of ice, this would be some time in the summer. There wouldn't be more than a few hours or even minutes of dark.
This takes place in a fictitious city in Alaska; however it is easy to tell that the location is not filmed in Alaska because the mountains with snow are C.G.I. and Alaska is so far north that the hours of lightness and darkness exceeds those depicted.
The sheriff tells the mother of a suspect in custody, "If nothing happens, you can pick him up in the morning." It is in reality the opposite. The B.A.U. had said earlier that if nothing happens, the suspect should essentially stay in custody, as they would know that they had the right guy, because he couldn't kill anyone.
When the BAU is inspecting the murdered fisherman's body, Reid notes that it looks like the unsub took a piece of the victim's body. When Hotchner asks what piece, Reid replies, "Hard to say, but judging from the location I would guess: liver or spleen."
Human livers and spleens are on opposite sides of the body. Surely a learned individual like Dr. Reid would know which organ based on the side of the body of the wound he was examining.
