Ever notice that some of the nations with the longest prison sentences, also have high crime rates and reoffending rates?

Or the many examples of crime increasing as sentence length increases?

Or the studies that have shown people sent to prison for a crime have higher reoffending rates than people given community sentences?

Study after study, and real life example after example shows that punishment is a very ineffective way of changing behaviour.

Complete impunity also does not change behaviour, we are talking where people can commit crimes and there is no punishment or even approval.
