Continuity mistake: Season 2 - Episode 16 - "Protest": Near the end when the guy is threatening to drop the nitroglycerin, he drops the test-tube and it lands on a red mat. However, when the agent picks it up, there isn't a mat anywhere near the test-tube.

Amita Ramanujan: Charlie, where did you learn all this stuff about assassination?
Charlie Eppes: If I told you that I'd have to kill you.
Amita Ramanujan: Okay, seriously.
Charlie Eppes: Seriously.

Thirteen - S4-E4

Trivia: The episode revolves around a man killing people with the same first names as the thirteen apostles (Mary Magdalene being the 13th), and killing them in a similar fashion in which the apostles died. At one point, Colby and David find a box with a mannequin's head in it. This is a reference to the film Se7en, in which seven people are killed for committing one of the seven deadly sins. The film ends with the main characters finding an actual head in a box.

In Plain Sight - S2-E8

Question: This question is about the mistake where a SWAT officer has a magazine backwards in his MP5. I know this would be impossible on a real weapon. But, how could it have happened in filming? Rubber cast weapon? Very badly worn prop weapon? Set armourer with a hammer and no clue?
