Interesting that Jacob gets a completely different standard of proof to me
but fine, I'll look into it. On the one hand USB is not a trivial protocol,
otherwise USB sticks wouldn't have microcontrollers. On the other hand
everything still goes through the CPU which is why USB is so much slower
than DMA alternatives. You might be right but forgive me for not taking
your word on it.

I don't think it is just that. Even if it is clean on purchase, after a
compromised Tails session it is theoretically a place to hide malicious
code to subsequently comprimise all future sessions.

I agree this is a radically different threat model. Tampering with the
Tails kernel or rootfilesystem at rest on a USB stick and tampering with
device firmware are completely different ballparks.
