Do TRCs Always Do What They're Supposed To?

After just a few days of testimony, the TRC is provoking strong reactions. Yesterday one of the disarmed warlords accused one of the people testifying of having been paid to impugn the warlord's character. (More here.) The warlord guy warns that the TRC process will tear the country apart. Of course, the warlords of the world have every reason to want the process to stop.

Is this what always happens with a TRC? Do people always say 'this will only make things worse!'? And does the TRC process ever lead to violence? We need an interview with a TRC expert.
