HOW DOES ONE OBTAIN 'OFFICIAL WHISTLEBLOWER STATUS'?
Did Cain/Cain's Attorney have a joint prosecution agreement with the DOJ?
JOINT PROSECUTION AGREEMENTS
(5)—Sharing Privileged Information Between Government and
Relator: The Joint Prosecution Privilege.
Sharing of information between the Government and the relator does not waive
either the attorney-client privilege or the work product protections. The courts
have long recognized that communication between two parties with a common
interest or communications between counsel and such parties in the presence of
the other party with a common interest does not waive either the attorney-client
privilege or the work product doctrine.6
The United States District Court for the District of Columbia has now expressly
ruled that information shared between the relator, his counsel and the United
States is protected from discovery by the joint-prosecutorial privilege.75
In fact, the unique relationship arising from the statutory requirement that the
relator serve upon the United States a “written disclosure of substantially all
material evidence and information the person possesses”79 requires the sharing of
work product generated by the relator and his attorney in order for the case to
proceed.80 Such material disclosed to the United States is protected from
discovery by the joint-prosecutorial privilege.81

THAT SAID, THE FBI RAID ON THIS WHISTLEBLOWER IS VERY ODD!
