The CIA contains agents, and hires contractors, who are drug dealers.
They do this (they think "rationally enough") to make money to spend on operations that are not funded by the United States Government, and in order to keep those same operations a secret from the United States Government.
This is treason against the United States, the penalties for which includes death.
There shall be no CIA operation not funded by the U.S. Government, nor shall any monies obtained through any means by the CIA go unreported to the Government of the United States.
Anything less is treason against the United States, the penalties for which include death.
