Corpora: Legal corpus?

[Pulie Thetela]

I was wondering if members would mind giving me information of any known corpus of spoken legal texts (e.g. witness testimony, direct and cross-examination of witnesses, judge/jury summations, sentencing, police interviews,etc.). I am working on interaction in courtroom discourse, and I need a large corpus as  reference for a thorough analysis and research.
Will appreciate your help.
