Even in Prison, This Professor Never Stopped Teaching Liberty and Love

In Dr. Doan’s case, the prison cell did not prevent him from fighting for what he believes. In fact, prison only made him stronger. It made him resolve to commit his entire life to human rights and liberty—and not just for himself but for others, for the Vietnamese people, and for the oppressed anywhere.
Even in prison during those two decades, Dr. Doan taught fellow inmates to understand liberty, love, compassion, and responsibility. In spite of what he’s been through, he did not and does not express hate of any kind.
