Confused by aspect of plot (SPOILERS)
If the perpetrator was using torture in order to extract information in an interrogation, how did the victim speak in order to give the information sought if his/her vocal cords were paralyzed by the pincers in order to stop the sounds of screaming that would come from the torture?
They were rendered speechless, no?
Did the interrogator make them write DOWN the information sought? That part of the plot confused me.
