The only tool we have for predicting the future is study of the past, however imperfect that is. During the 20th century, Soviet Russia, Nazi Germany, and Red China experimented with restoring "order" by mass incarceration and elimination of civil liberties. Of the three only Germany has emerged as a modern, democratic, nation state, and that was only after committing genocide, waging a disastrous war, unconditional surrender and foreign occupation. Both Russia and China are continuing with authoritarian governments with central planning and non-existent civil liberties. What does 20th century history tell us about El Salvador's future?
We, in the United States, are now reconsidering the strategy of mass incarceration to reduce crime. There are benefits to living in a constitutional democratic republic and those benefits include open discussion of failed policies leading to gradual change.
