Action items
- Read the article's evidence and "investigation" or "reception" sections, and open its cited sources.
- Before sharing anything on this topic, run it through the fact-checkers above.
- Rely on coroner, court and official investigation records.
- Be wary of 'hidden clue' videos and anniversary-timed rumors.
- Wait for verified reporting from multiple independent outlets.
- Watch for 'crisis actor' claims, which have harmed real victims' families.
- Notice when a claim blames a whole group for a secret plot. That's a classic sign of hate propaganda.
- Check resources from the ADL, SPLC or national equality bodies.
- Report hateful content on the platform where you saw it.
- If someone you know believes it, ask what evidence would change their mind, and share one good source, not ten.
Prevention steps
- StopNotice a strong emotion (anger, fear, 'they don't want you to know') before you share. Pause first.
- Investigate the sourceWho is making the claim, what's their expertise, and what do they gain if you believe it?
- Find better coverageRead laterally: open new tabs and see what independent outlets and fact-checkers say.
- Trace claims to the originFind the original study, video or document. Check dates and whether quotes are cut.
- Ask what would change your mindReal theories can be tested. If every piece of counter-evidence 'proves' the cover-up, it can't be.
- Count the peopleBig secret plots need thousands of people to stay silent for years. That rarely happens.
- Talk, don't mockWith friends or family, ask questions, listen, share your own sources calmly. Shame backfires.
