Father Peter is an American priest who has spent more than 40 years practicing liberation theology all over Latin America. Fifteen years ago he moved to Ciudad Juarez. Father Peter lives alongside the poor and working class -- shopkeepers, maquila workers, and small time drug dealers. At 86 years old, he splits his time between being a political activist, trying to change US foreign policy around Latin America and being a neighborhood priest.
