Luckily Guiliani gave it to state level LEOs in Delaware, which are separate from the corruption in the FBI higher ups.I don't think the laptop is in good hands with the crooks in the FBI tbh.
The emails bit connecting Hunter and Joe are the real important bits, because it's kinda hard to prove Joe knew about any CP stuff. It certainly makes things look worse for Joe, but doesn't directly implicate him in illegal stuff.
The emails referencing Joe in the bribes/pay-offs are the ones that are really bad for him.
And I want to second @Spartan303 guessing Hunter will be 'suicided' for this. He may already have been, as people are still looking for him it and have been for a while it seems.
