When they're out, his job is to watch them. Through the years, Dutra has been trained by some of the best experts in the nation. People don't do things they don't want to do. It starts before the offender is sentenced. Dutra and other agents write presentence investigation reports about offenders.
Judges rely on the reports when deciding how to punish sex offenders.
In the reports, Dutra details the history and crimes of the offenders. That's what makes them different from the balance of the criminal population. They had a wife, kids, job and seemed normal except for that one glaring anomaly. The most common offender Dutra sees is the guy who assaults a young teen, perhaps a baby sitter or a stepchild or somebody else he knows. Dutra's clients are almost exclusively males.
