The record first. Commentary second. This library separates official filings and sworn proceedings from press coverage and clearly marks materials that have not been publicly located.
Inclusion is not endorsement.
Investigative affidavits and charging papers state allegations offered by law enforcement and prosecutors. They are not findings of guilt. Hearing transcripts and video preserve what was actually presented in court. Third-party transcripts are provided for navigation and should be checked against the video where exact wording matters.
