Gary Webb draws from thousands of pages of once-secret files from the CIA, DEA, and FBI, the L.A. Sheriff's Department, and recently declassified papers from the Iran-Contra investigation. Together with Nicaraguan journalist Georg Hodel, Webb interviewed former members of the Contra drug ring, as well as former federal prosecutors, CIA and DEA agents, and former Central American police officials. This book shows how the L.A. crack market flourished through a breathtaking combination of government negligence, greed, and criminal conduct. It also demonstrates that the U.S. goverment agencies, including the CIA, the DEA, and the FBI, were aware of the activities of this well-connected drug network throughout its long existence and did little or nothing to stop it. Indeed, in several instances documented here, the Justice Department, the CIA, and the secret National Security Council unit run by Oliver North, took extraordinary steps to protect the ring from public exposure.

If you dig there, you'll sooner or later hit upon the weird discrepancies from reality that Wikipedia article has. It mixes unrelated cases with genuinely disturbing ones like McCasland. Who wasn't demented at all.
"Housecleaning" refers to the practice of killing prospective leaks. It doesn't make much sense to kill them once they've talked.
Killing is a last resort, mundane leaks are retaliated against by revoking clearances and destroying careers that way.
Note that the Espionage Act of 1917(!) allows to treat whistleblowers like foreign spies and deprives them of arguing, their leak would serve the common interest.
Actual cases are usually ruled "suicides" or "accidents", but obviously aren't:
Danny Casolaro (1991): "The Octopus" Investigation
Gary Webb (2004): The "Dark Alliance" Expose
Dr. David Kelly (2003): Iraq War WMD Leaker
John P. Wheeler III (2010): Pentagon Insider
... there are many others. You only find what you look for.
Afghanistan after first overturning the Taliban had the biggest increase ever in drug production ever when the CIA was running the country.
