M asked people in S whether or not they knew about the torture inside the prison. They told him that they knew. In fact, they knew every move, every word said and everything happened in the prison because they recorded everything. They also knew about the messages stuffed inside the "balls", and hole in the fence, etc. When M asked why they didn’t stop the torture, they replied that they couldn't change the mentality of M’s people. They could not force the prisoners to love one another and stop torturing their own. They also told him that one's worst enemy, the enemy which would cause the most damage, was often from within, not without.
