You'd be surprised at what can occasionally be found.
I think that I might be able to cover my tracks, but I'm definitely not sufficiently certain to stake my freedom on it, there's always a chance that I'd make some mistake and they happen to be more thorough than I am, and the same applies for everyone (e.g. including authors of APT's employed by the major intelligence services around the world); a 90% chance of getting some extra money on top of what he got isn't worth a 10% chance of criminal prosecution. Knowing that the machine is going to be analyzed by someone with a lot of resources is a sufficient deterrent IMHO.
