Ironically - there was a way to ensure you wouldn't be punished. That's how the TRC worked - people who confessed of political crimes, and held nothing back, would get amnesty. The deal was - for giving the families closure, and letting them have the answers of what really happened, we would let you off.
Many people took advantage of it, and we learned a lot that would otherwise have remained secret. Even some security police testified before the TRC for amnesty.

These ones chose not too - they chose to keep the secret and leave the families with that hanging question. But in so doing, they also gave up the option of amnesty. Let the living ones be charged. Let justice run it's course. They had their chance at amnesty for honesty. They didn't use it. Now the truth must come out through the justice system.
