[plausibledeny]

Similar to the way the FBI doesn't record interviews, because it affords them an advantage in court. Who are you going to believe when there is no audio or video, an FBI agent or someone accused of a crime.

Which is exactly what's happening right now in the Sussmann case (brought by Durham), he's being accused of something based on the memory of an FBI agent when a videotaped interview would have made it trivial to prove/disprove.
