The Church Committee
The United States Senate investigating the CIA and the FBI, with subpoena power and testimony under oath.
Who released this.
A separate branch of government examining the agencies, rather than the agencies reviewing themselves. This is about as independent as a US government source on this subject gets.
What this collection cannot tell you.
Constrained in one specific and important way: by the time the Committee reached MKULTRA, the programme files had already been destroyed. The Committee was working from what survived, and said so. Its silence on a detail is often the destruction speaking, not the Committee.
We say this on every collection because an absence in a curated release is evidence about the curation, not about the world. Why that distinction runs through the whole product.
