Documented 1927 levee dynamiting seeded later distrust of flood authorities

Evidence

The Great Mississippi Flood lives vividly in the collective memory of the region: in 1965, during Hurricane Betsy, when the levees were breached by storm waters surging into Lake Pontchartrain, some New Orleans residents again felt certain that city leaders had blown the levees to save the wealthier parts of town. Then, too, according to local lore, survivors said they heard explosions that sounded like dynamite. — Anna Merlan, Republic of Lies, 136

Categorization

• XREF: Directly supports the reader’s core goal: conspiracy belief does not require irrationality when a real historical injustice (prior chapter’s levee dynamiting) grounds it — ties to vault claims on social-identity/threat mechanisms behind belief. — connects to: In 1927 New Orleans dynamited levees to save itself by flooding black communities — Anna Merlan, Republic of Lies, 128; The 1927 flood displaced half a million people and forced enduring migration — Anna Merlan, Republic of Lies, 135
• SEED: Article angle: ‘conspiracy theories are rational when the government really did it’ — a 1927 precedent directly producing 1965 and 2005 (Katrina) suspicion is a strong case study.
