It depends on what the trial was about and where it was held. I know that the AARC Public Library holds some trial transcipts for US cases and CNN.com holds some. Your best bet is to try googling the name of the accused followed by trial transcipt and news paper sites etc will be able to let you know about the transcipts online. If you want it in person your best bet is to contact the clerk of the court where the trial was held and they can tell you where the transcipts are available to view.
