INFILTRATION OF THE GOVERNMENT BY MEMBERS OF SUBVERSIVE OR CRIMINAL ORGANISATIONS FOR THE PURPOSE OF FURTHERING THE INTERESTS OF THOSE ORGANISATIONS
“A nation can survive its fools and even the ambitious, but it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and he carries his banner openly. But the traitor moves among those within the gates freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself.
For the traitor is no traitor, speaks in the accents familiar to his victims. He wears their faces and their garments, and he appeals to the baseness that lies deep in the heart of all men.
He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of a city. He infects the body politic so that it can no longer resist. A murderer is less to be feared.”
CICERO
