Dr. Lance Williams
When a lyric, a photograph, or a post becomes evidence, the question is what it actually communicates — not what it appears to mean from the outside.
“In my 25 years of litigating serious felonies, Lance Williams has easily been the most natural and reliable expert witness I have ever presented.”
“Extremely knowledgeable, up to date, and uniquely qualified as an expert in the field of gangs and urban communities. His contribution certainly helped our team arrive at the successful outcome.”
