After the tragic shooting at the Trump rally in Butler, Pennsylvania, where Thomas Crooks opened fire, the FBI’s handling of the investigation has drawn renewed scrutiny. The initial failure to identify and track Crooks’ alarming online activity has raised questions about the bureau’s effectiveness and its ability to assess threats in real-time. The agency’s previous claims that Crooks had a thin digital presence have been contradicted by new evidence, including a significant digital footprint that was supposedly easily accessible with standard investigative methods.
