Big secrets stay secret when no one knows the whole secret
Each participant gets specific instructions and learns almost nothing about the rest of the plan.
Who Killed JFK? · Who Killed JFK?Keeping a big plot secret does not require keeping the group small. It requires making sure almost no one knows the whole plan.
How could so many people take part in a secret plot to kill President John F. Kennedy without exposing it? The writer who researched Richard Case Nagel, who argues that multiple shooters were involved, says the answer is compartmentalization.
Compartmentalization means each person learns only what is needed for a narrow assignment. He put it this way: "It was all compartmentalized. Everything was done on a need to know basis."
Applied to Dallas, his view was that the shooters were separate from one another. He said, "Most likely, none of the shooters were aware of the others. So in that sense, they didn't work together."
The CIA agents spoken to for the account describe the same practice. They said that "people in operations like this would be given very specific instructions of what they were expected to do" and that "They would know little or nothing about the other people involved."
The design is meant to limit damage if one person is caught or talks. A participant handed only a small piece of the work has little to reveal about the rest, because he was told little about anyone else.
Questions people ask
Is compartmentalization a real method, or just a theory about this case?
It is standard practice in intelligence and military work, as well as in some corporate and law enforcement operations. The idea is to limit damage if one person is caught, defects, or talks. Even people with high clearances often see only the material needed for their assignment.
Why doesn't compartmentalization stop leaks entirely?
They still might, but what they can reveal is limited. A driver may be able to describe his route, or a lookout his post, without knowing who gave the order or who else took part. Investigators then have fragments that are hard to connect into proof of a larger plan.
What is the downside of organizing work this way?
Separation makes coordination harder and increases the chance of mistakes, delays, or misunderstanding. Leaders accept that cost because the greater risk, in secret work, is exposure. Fewer people knowing the full picture means fewer ways for the picture to get out.
