	In my experience, things are rarely cut and dried in the way you
describe them.  Policy needs procedures, standards, and implementation
to back it up.  These in turn require proper training, education,
testing, detection, and response in order to assure that the reality
meets the theory.  In a properly set-up protection environment, these
sorts of events don't happen except in rare circumstances, and in those
rare cases, there is a management procedure developed to deal with it.

	In a well-designed organizatoinal environment, protection
management exists at the top levels of the organization, and there are
channels for crossing any boundaries.

That would work too, for a few minutes, and then you might get fired.

For protection to be effective in an organization, it must be built-in to the
way the organization as a whole operates.

In my personal experience, protection more often fails because the
person who manages the network got the job by being the person who did
backups of the server before the previous network administrator left. 

My interpretation of both of these examples is a lack of adequate
understanding and attention by management.  It seems pretty clear that
without adequate understanding and attention by management, any
component of an enterprise is likely to fail - whether it be information
protection or manufacturing.  The solution is to help management better
understand the issues so that they can make more enlightened decisions.
