Many see Norway as one of the most utopian modern countries, citing its citizens' happiness, its booming economy, and incredibly low crime rates. Experts have said these low crime rates are a result of the country's progressive take on the justice system, which focuses on rehabilitating its criminals instead of punishing them.

Criminals convicted in Norway have a maximum sentence of 21 years, even for acts like treason and mass murder. Norwegian prisons are considered to be the nicest in the world, offering comfortable amenities and relatively low security. They also have effective rehabilitation programs in place that provide former criminals with healthcare, education and even pensions.

Do these progressive policies really result in lower crime rates? And if so, what can the U.S. learn from them?
