To stick to the facts, LA's biggest cocaine supplier got his stuff from a pair of Nicaraguans were members of the CIA-backed Nicaraguan contras raising money for the organization. A journalist named Gary Webb covered the whole thing, who later murdered by two gunshots, and his death was ruled a suicide.
There was never any evidence to begin with. The author of the often cited investigative report even refutes the assertion that the CIA was involved. It’s pure fantasy.
from what I have been able to determine, this does not seem to be true—people who die from multiple self-inflicted gunshot wounds to the head seem to be quite few and far between.
