One thesis you could take is that the US, with the largest incarcerated population in the history of the world, could stand to be a little bit less harsh in their sentencing.
Oh sure, but if we're going to get at the big problems in the US criminal justice system, I think there's dozens of broad, general problems (living conditions, privatization of a "public good" service, general focus on punishment vs behavioral reform, etc) that would do better at addressing the issues for the most people involved.
Also, as I was previously trying to state, I feel that we should address this issue by generally changing/lowering sentences. If we can be compassionate towards woman convicts, why not men?
