I don't think it's going to be that easy.
1. Nobody will believe them.
2. This isn't a simple matter of "destroying a laptop." The e-mail files they found were probably not on this computer, but in a cloud storage location that was accessible through the computer.
3. The story from a couple of years ago, involving a hack of 500 million Yahoo accounts, makes it impossible to know who else might have these e-mails.
4. Too many hands in law enforcement (NYPD, multiple FBI field offices, etc.) have seen this information.
5. If the Wikileaks dumps of John Podesta's e-mails have told these people anything, it's that they have to go through their lives with the expectation that every one of these e-mails is eventually going to end up in the public domain.
Sure the emails might show up later, but the life and death struggle for them is to keep the DOJ in corrupt hands to protect the corrupt.
This is all true.
But they may not be thinking rationally. Rather what ever it takes to win on the 8th. Then it all goes away.
re: #3
the proximate cause for the Yahoo hack were the Huma e mails
I keep thinking that Rudy G. still has some friends in the NYPD, and maybe the FBI too...
