The Depravity Scale research is ongoing, and we welcome public participation at www.depravityscale.org, in order to refine the significance courts should give to different qualities of a crime at the time of sentencing. If Casey Anthony is found guilty, findings from the Depravity Scale research will one day educate courts about what intent, actions and attitudes distinguish a crime -- or do not. This promotes fair, evidence-based sentencing that is color, gender, and socio-economic blind, and driven by public input.
