Factual error: When Roy is electrocuted and falls from the roof, after Karen uses the defibrillator paddles on Roy, she lifts both paddles, looks at the EKG monitor and says "He's converted." How exactly could Karen have known that he's converted? It's impossible for the EKG monitor to show anything at all. Either the defib paddles have to be in contact with Roy's body for the "quick-look" to get a reading, which they weren't, or the ECG electrode discs have to be on Roy's chest connecting him to the EKG monitor, and they weren't. As an aside, just watching Marco having problems attaching the air mask, and quickly glancing up towards the camera frustrated, then giving up is priceless.
Factual error: When Michael fills the tank with water (below the stock room), he then strips his clothes off, and slides down a pipe and into the water at the bottom of the tank. Since the water level was way above him, the pipe he slid down and the access to get there would have been flooded also. There was no water in the pipe he slid down, so for that area to be dry, it would have to be above the water line.
Factual error: Tom Keen watches an arms deal. The supposedly German plates of the BMW read "DD17-36F9." This, however, is not a possible combination in Germany, as there would not be numbers in the first half, nor a letter after a number in the second part. [exceptions from the first being the most important officials' cars like the federal president's, but even then the latter applies]. Furthermore, no more than 4 numbers can be used, except for in police and military vehicles (which also never have a letter after a number, and start "Y" for military, or "DD-Q" for Dresden police). "DD-F1736" would have been a correct plate for the town of Dresden, for example. (00:23:15)
Factual error: Calleigh Duquesne frequently wears completely inappropriate clothing throughout the whole series. She often wears blouses that are so low cut that the neckline is below the lower curve of her breasts. No officer of the court in the US would be allowed to dress this way. There is no grey area here, and this is not a character mistake - first time a CSI turned up at work dressed like that, she'd be sent home to change. Second time, she'd be on suspension until she agreed to change her dress standards. Also (and this regularly happens in CSI: NY as well) she is regularly wearing high heels - also a certain no-no for as CSI. Incidentally, male CSIs have equally strict dress standards.
Factual error: The tanks, half-tracks and self-propelled guns are modern American vehicles painted in a a bright yellow color rather than a muted desert sand color. The only vehicles which actually did see action in North Africa in WW2 would have been the M-7 Priest Gun Motor Carriage and the M3 half-tracks being used by the Germans in "The Rat Patrol."
Factual error: Sgt. Saunders is looking at a color photo of his kid brother in a letter from home. Aside from being prohibitively expensive for the average family to afford, color photos were not common. Also, the wartime rationing of photo chemicals for color film used by civilians would not be available.
Factual error: Air Force One landed in Wichita, Kansas. The local coroner claimed Jurisdiction for Wichita County. The city of Wichita, Kansas is in Sedgwick County, in southern Kansas. Wichita County, Kansas is in western Kansas, about 250 miles from the city of Wichita. (00:05:40)
Factual error: In the whole episode, Romania is depicted as a monarchy with the king in a position that allows him to make political decisions. However, Romania ceased to be a monarchy in 1947. By the time depicted in the episode (circa 1997), Romania was a republic and its head of state was the president. Members of the ex-royal family did not hold any positions in the Romanian government and were certainly not authorized to represent Romania in international events.
Factual error: Alice and Kate's little reunion underwater is disrupted by policemen that fire at them, and one of the shots reaches the transport truck, ignites it and makes it explode. The scene is baffling; forgetting the complete disregard for fellow policemen in the vehicle, how would bullets have enough strength to penetrate into an armored truck deep underwater, reach a critical weak point from that angle (the truck is upright, they should be barely get to shoot the roof of it) and still underwater cause inside the completely immersed vehicle a spark that would ignite fuel and make the whole truck explode?

Factual error: The briefer on the oil platform mission says the platform is 12 stories, and 80 million square feet. Doing the math, that makes it half a mile per side if completely square. It is nowhere near that size as shown. The largest oil rig in the world - Berkut in Russia's Far East - has a combined deck area of only 342,000 square feet. (00:13:35)
