Imprisonment Should Only Be for Violent Crimes

What is the purpose of prison? We aren't being cheeky, because
this question is a large basis for our discussion this episode.
Is prison just used as a punishment, or is it to protect good,
law-abiding citizens from being hurt by criminals? Is it both?
Regardless of the answer, should we be looking to tailor
punishments to the crime instead of using prison as a catch-all
for all crimes? Join the Controcast as we explore this maze of
morality in crime and punishment.
