This is not true, at least in the US.  Log files can be entered into
evidence unless you can prove that the log files have been tampered
with.  The "possibility" of changing data does not make evidence
inadmissible, only proof that data has been changed.

I don't see why a Norton Ghost image is any different than a tape
backup, and backups have been regularly entered in as evidence in many
famous cases, such as the Microsoft anti-trust case.
