It is extremely within the CIA's ability to plant a VM on a computer. It is not established that the password was known only to "the defendant," as if the CIA alleging that is the case makes it true.

Extensive file system logs are also easy to generate. They could also be legitimate access logs but the VM itself was compromised by the CIA.

IRC logs are literally a text file. It would be extremely easy to fake those as well.

Do you really think the CIA is incapable of doing something like this? Hell, if I were able to obtain the password used to encrypt the VM (easily within the realm of possibility with CIA resources) I could do each one of these things myself.

The CIA has many extremely clear motivations to set this up, and they absolutely have the means to do so. They have also in the past been caught doing far, far worse. In addition the Vault 7 leaks contain instructions for doing exactly what many suspect here -- planting something like CP covertly in order to frame someone.

Come on, man.
