Honestly, if I'm the defense, this has gotta be awesome, right? Now, I'm not a lawyer, but I have watched Boston Legal twice, so that's basically the same thing, and what I'm hearing is these people want to get up on the stand and show the jury a video which either:
A) to the particularly inattentive, shows the victim clearly alive, or
B) demonstrates that even video evidence can be completely fabricated from whole cloth, and the opposition is more than capable of doing so to serve their own interests
Barring the staggeringly unlikely event that the defendant goes full-on Perry Mason Perp and outright says "hey, sorry I killed you, man" to the hologram, this seems like a pretty sweet deal.
My class was set to graduate right around the time the pandemic hit and a lot of people ended up graduating late because the school literally couldn't offer the classes they needed to finish their degree. Anyone to whom your date of graduation is actually relevant likely isn't going to bat an eye at anyone who was in college within the last 5 years graduating a couple months late.
And, of course, there's that old stand-by moral of "the only reason it seems like all your peers are doing better is because the ones in the same situation as you aren't going on social media to brag about it." So don't rely on that as a metric too heavily.
