Two Sources

Thousands of people chased one rumor for three weeks. Two reporters built one case for twenty-six months. The difference was not intelligence or effort. It was a rule.

GRANTDESK SIGNAL LABORIGIN COUNT
VOLUME: VERY HIGHSOURCES: 1
WKNR · DETROIT
12 OCT 1969

A phone call reaches a city.

A caller got through to Russ Gibb, a disc jockey at WKNR. He said Paul McCartney was dead, the Beatles had hidden it, and their records contained the proof.

The caller told Gibb to play a track backward. Gibb did it live. His signal reached tens of thousands of people at the same time from a voice many heard every day.

Within about three weeks, newspapers and television stations across the country were running the story.

MICHIGAN DAILY
14 OCT 1969

The clue list gets an author.

Two days later, a University of Michigan student named Fred LaBour published a piece announcing McCartney's death and listing “new evidence.”

LaBour says he invented most of the clues as satire. His original readers had context. When stations and other papers repeated the piece, the context fell away. What reached another city sounded like “the Michigan Daily reported,” not “a student wrote a joke.”

The article gave people a shared checklist. From then on, thousands were not independently discovering clues. They were checking the same list.

SOURCE TRACE
RUN BACKWARD

Ten thousand people. One source.

People in Cleveland and Sacramento found the same clues without knowing one another. That looked like corroboration because the results matched.

The missing step was tracing where each person got the checklist. Agreement counts as independent only when the sources could have gotten it wrong separately.

Where did each one get it?

WATERGATE
17 JUN 1972

Five men inside an office.

At about two in the morning, five men were arrested inside the Democratic National Committee offices in Washington's Watergate complex.

The Democratic National Committee runs the Democratic Party's national campaign operation. Breaking into it during a presidential election was not an ordinary office burglary. The men carried cameras and electronic surveillance equipment, not things they could sell.

The next morning it was a small story. It took twenty-six months for the case to help end a presidency.

NEWSROOM STANDARD
LOCK SIGNAL

The rule.

If information came from a source who would not be named, the Washington Post did not run it until a second source, independent of the first, confirmed it.

Two people who heard the same third person are one source and an echo. A person who agrees after you reveal what you already know may only be agreeing with you.

The rule killed stories reporters believed were true. That cost was the point. A standard matters because it can stop you from doing what you want.

How many sources is this actually?

Group statements by origin, not by speaker.

RECORD WORK
1972–1973

Not a garage. Paper.

The popular picture is a shadowed parking garage and a source in a trench coat. The actual work was campaign filings, phone records, payrolls, and repeat interviews.

A record holds still. A phone log shows the same call every time you look. That makes a witness more useful because the question can become exact: why did this number call that number on this date?

On July 16, 1973, White House staffer Alexander Butterfield answered a routine Senate question and confirmed that a taping system had recorded the president's conversations. Nobody had started the question looking for a taping system. Thorough work made room for the answer.

SAME TEST
BOTH CLAIMS

What would have killed it?

Do not begin with “Do I believe this?” Ask what finding would end the claim, then see whether that finding exists.

A living Paul McCartney should have ended the death rumor. He was alive, photographed, and interviewed. The rumor absorbed that evidence.

The Watergate case could have died if financial and communication records failed to connect the burglars to the campaign. Investigators obtained the records. They showed the opposite.

Name the thing that would end it

Same three questions. Both cases.

Open the fields in either case. The procedure stays the same.
COMPARE SIGNALS
KEEP SCALE

Both were investigations.

RUMORthousands of people

Three weeks. Great energy. One shared checklist. Nothing that survived contact with a living man.

WATERGATEtwo reporters

Twenty-six months. Records, repeated interviews, and a rule that refused to count echoes as confirmation.

The next three weeks run on three questions.

  1. Where did this person get it?Not only what did they say. Who told them, and who told that person?
  2. Could these two sources fail separately?If both read the same post, they are not independent.
  3. What would change your mind?Name it before searching so the test does not move after the evidence arrives.

Two independent sources. The method is simple. Following it when a good story is waiting is the hard part.
