O. J. Simpson murder case
Kohn has represented whistleblowers in the O. J. Simpson murder case, the World Trade Center bombing cases, the Oklahoma City bombing case, the Linda Tripp-Privacy Act case, and the Bradley Birkenfeld-UBS AG tax evasion case. One of the firm's clients was Dr. Frederic Whitehurst, a supervisor at the FBI Crime Lab, who blew the whistle on the Bureau and its tainting of forensic evidence for use by prosecutors. Kohn introduced Whitehurst's 1995 testimony before the House Subcommittee on Crime.
