Policy Scenarios The index below points to a set of policy scenarios, practice issues or more general questions related to crime and offending, being explored through simulation. We intend this to be a growing repository of quantitatively analysed criminal justice ideas. The results published here do not represent a complete assessment of each example. In particular the costs of implementing and operating realistic alternatives, compared to no-change, are not yet assessed. Rather, the examples at this stage are exploratory and do not represent fully worked out proposals.
In some cases it would not make sense to over-analyse particular ideas. Some are included not because they are particularly realistic but because they help provide insight into the dynamics of the criminal justice system and therefore help assess, on more general grounds, whether a particular direction would be more or less attractive, such as whether they would be likely to add to the size of the prison population or reduce it, or would make a positive impact toward rehabilitation objectives Examples of these include such issues as honesty in sentencing, three strikes policies, and executive release.
However, all the examples are being kept under review and will be updated periodically, to reflect extensions to the analysis of each case, improvements to the simulation engine and its scope, and in terms of new questions that are being investigated.
