Of course.  How would you propose to make a system truly secure if a hacker
has physical access to the machine?

If I encrypt my filesystems, nobody with a liveCD can read the filesystem,
but even then there must be something either in hardware or software that
provides the key to decrypt that filesystem, which would be available to a
user with physical access.
