The boom of big data and predictive analytics has revolutionized business. eHarmony matches customers based on shared likes and expectations for romance, and Target uses similar methods to strategically push its products on shoppers. Courts and Departments of Corrections have also sought to employ similar tools. However, the use of data analytics in sentencing raises a host of constitutional concerns. In State v.

This article explores certain equal protection and due process arguments implicated by Loomis.
