If your lap top went missing and turned up months later in the hands of people who had stolen it, or received it as a stolen item, and many of whom had accessed the laptop you would very reasonably deny any knowledge of anything nefarious on that laptop.
As would anyone.
The people handling this stolen laptop were political opponents of Hunter Biden’s farmer.
By all means, put that in front of a Grand Jury, it’ll not get as far as. Trial Jury and if it does Hunter Biden’s legal team will explain ‘reasonable doubt’ to the Jury.
