On the laptop, there are two things we can say for certain.
A. Nobody else could have know if by destroying the laptop they would destroy any copies that RFG may have made prior to about 10:00 AM on 4/15/05. Even someone not technically savvy would realize that.
B. Unless someone else viewed the laptop prior to RFG bringing it to Lewisburg, they would have no idea if the data they wanted to see was actually on the laptop.
A Expanded: I can understand someone wanting to destroy hypothetical incriminating information on the laptop, but, unless the person was an idiot, he would have to know that digital data is easy to copy. RFG could have copied it to either or both of two other computers, He could have, even in 2005, downloaded it a floppy disk, a CD-ROM, or a flash drive (which were around since 2002). He also could have printed it and kept it on file. He could have done that as late as 10:00 AM.
B Expanded: It is, in theory, possible that someone who wanted private information saw RFG put it on the laptop prior to 4/15/05, though very unlikely. That person would then have to convince RFG to bring the laptop to Lewisburg. That person would also have to assume that the data was still on the laptop when he brought it.
If there was even a short period (less than an hour) between the person knowing the material was on the laptop (unlikely) and RFG leaving, there was no guarantee that it would not be deleted. If this was something very confidential, and high valued, RFG could have copied it to another computer or a removable device, where it would be safer.
As I said, the laptop could be huge, as it can point to walkaway or suicide. It may, and likely, is not huge, if RFG was the victim of foul play.
