So the way the lawyers are approaching this evidence is their usual cavalier approach to truth. They are not attempting to establish “my client never said that,” but just trying to poke holes, “this video of my client saying that is not sufficient proof that my client said that.”
There is for example no statement under oath from Elon, “that video was a fake, that absolutely never happened.” Even without that, there is no paper trail of “my client maintained a very consistent messaging that this was not fully autonomous driving and you need to always be vigilant... this isolated clip is so strange that we need to seriously entertain the idea that it was deepfaked.” That sort of stuff.
Regarding the faithful wife accused of cheating, I mean, there are lots of valid ways to investigate. First questions are “where did this video come from, where do you believe it was filmed, why do you believe it is your wife rather than someone who happens to look a lot like her,” etc. ... Normally a PI would be claiming “I followed her to so-and-so motel, I took this video legally from outside” and even then you might get objections from a decent divorce lawyer, “this is a two-party consent state and my client didn't consent, this is unlawful surveillance,” yadda yadda yadda. But for a deepfake you have all those objections and more.
Look up “laying the groundwork” for “documentary evidence” and you will find that this fails to show chain of custody unless you can get that “guy saying he is sleeping with her” in the courtroom.
