Factual error: While the NCIS crew are working a crime scene, Ducky starts yet another parable about his past experiences, referring to the dating of an Indian skeleton by the caliber of the bullet, "a 40-75". He states that since he knew the year that the US Army used that caliber, he could accurately date the remains. Unfortunately for Ducky, the US Army never used a 40-75. It did, however authorize a contract for a 45-70 cartridge in 1873.
Plot hole: When Gibbs discovers the body in the hotel room he is on the phone with Kate. As Kate starts to describe the man Suzanne remembered, Gibbs interrupts and describes the dead man, including his tie. The camera then pans over to show the man lying face down. There is no way Gibbs could have seen his tie.
