Find the earliest reachable source
Reposts often remove dates and context. Work backward toward the earliest publication, then compare the audio, caption and stated location.
Inspect the edit
Cuts, repeated segments and mismatched ambience can change meaning without fabricating the underlying recording. Treat the edit history as part of the evidence.
State uncertainty precisely
“Unverified” is more useful than a confident guess. Say what is known, what remains missing and which observation would change the assessment.
