Peter K Enns discusses issues raised in his book, 'Incarceration Nation: How the US Became the Most Punitive Democracy in the World;â(Cambridge) tracing the influence of the public on politicians and of the media on the public and how the rise and fall of crime rates is reflected in similar moves in public opinion; he sees the recognition of the incarceration problem by Republicans, e.g.,Paul Ryan and Koch brothers as a positive and that this issue will likely be a subject of debate in presidential elections as the costs of imprisonment to the public through legislative budget needs becomes evident coupled with the judicial system not functioning as intended and that the African-American and Latino populations have been its primary victims; he also believes the ongoing reports of prisoners freed after serving long sentences for crimes they didn't commit has had a positive impact on the public view of incarceration.
