A fair point.  I'll use it when I'm explaining that you never know who did the access, only who is responsible for who did the access.  It is a bit harder to explain, though, because how you do the auditing depends on the underlying mechanism.  For example, with SAML, the delegation chain is in the assertion.  With Horton, the audit information is distributed through the system.
