Disagree, plus the encryption would still be in effect if you got the drives. Russia is actually good at being 1337 h4x0r5 and have always been in Ukrainian networks, even the ISPs from which they can "swim" anywhere. They can yoink encrypted files back to the motherland over the net and try to decrypt them and full-disk encryption is irrelevant for a remote hacker.
I don't know I just think "omg they'll find the hunter biden files!!" is retarded, especially considering how much time the relevant contacts have to just DFE.
