This is not true, at least in the US.&nbsp; Log files can be entered into<BR>
evidence unless you can prove that the log files have been tampered<BR>
with.&nbsp; The &quot;possibility&quot; of changing data does not make evidence<BR>
inadmissible, only proof that data has been changed.<BR>
<BR>
I don't see why a Norton Ghost image is any different than a tape<BR>
backup, and backups have been regularly entered in as evidence in many<BR>
famous cases, such as the Microsoft anti-trust case.<BR>
