## Summary

g1’s Fato ou Fake classified as false a video circulating on social media since at least October 15 that allegedly shows Leonel Brizola linking Jair Bolsonaro to militias and a death squad. The recording manipulates a segment from the first-round 1989 presidential debate hosted by SBT; according to the transcript reviewed by g1, Brizola does not mention Bolsonaro in the original material.

To trace the source, g1 used the InVID platform and a reverse search on Google Lens. Three tools detected manipulation: HiveModeration estimated a 99.4% probability that the audio had been altered with AI, while Hiya/Invid indicated a 99% chance that the audio was AI-generated, and Detector Mever/Invid indicated a 99% probability that the video was a deepfake.

## Why it matters (editorial interpretation)

The case illustrates how audio and video manipulation can recontextualize historical political material, attributing statements to a public figure that he did not make. The verification combined transcription, reverse search and detection tools, but the probabilities were estimates from the services used, not standalone proof.
