Audio problem: When Booth knocks on Decker's front door, there is no sound of the knocking, even though the dialogue and foley bird sounds are clear. Then, a few seconds later, he knocks again and there is still no sound of the knock. (00:08:58)
Visible crew/equipment: Just after Booth gets the codeword from Decker, we see a shot of him and a boom arm can be seen moving in the door's reflection behind Booth. (00:32:30)
Continuity mistake: The position of Carl Decker's gun in relation to the head of the head of KBC systems is constantly changing between shots. (00:29:00)
Continuity mistake: When the lawyer at KBC Systems slides the file to Booth we see the file reach Booth. Camera changes and it reaches Booth again. (00:17:10)
Continuity mistake: When Zac and Bones are discussing the fractured teeth, there is a security guard in the background whose position changes between shots. (00:15:05)
Continuity mistake: When Booth has the face off with the US Marshall's the van door is shut then opens itself. (00:10:00)
Answer: Answering my own question here but, having contacted various people involved in the production of Bones including Kathy Reichs, Hart Hanson, Eric Milligan, and Deirdre Lovegood who portrayed Taffet onscreen I finally have the answer. No-one know how she did it due to her constantly working alone. And she never revealed this information before her death.
