Technologists have used facial recognition techniques on the large archive of Parler videos filmed from the January 6 Capitol riots, Motherboard has learned. In some cases they have been able to track individual faces across different videos, pinpointing where a person was at specific points in time, potentially even if they did not use Parler themselves.

The news signals how archivists, hackers, and hobbyists continue to mine the Parler data for what they believe may be useful insights to provide law enforcement. It also highlights the fraught issue of facial recognition, which can often be inaccurate and require manual analysis to review, and more generally demonstrates the democratization of facial recognition.
