The Concept of Evidence-Informed Policy The main goal of the evidence-informed policy is to increase insights into policy decisions and empirical data roles. Systems can be useful or harmful, but by the use of substantial evidence, the government can have a positive impact. Ensuring balance in evidence-based programs increase public confidence and ensure greater diffusion of evidence-based interventions (Fagan & Buchanan, 2016). The use of evidence to make a decision is the right thing to do, but it rarely happens because the gathering of evidence within the government organization is hard. The Importance of Policy Evaluation and Assessment Policy evaluation and assessment using evidence-based programs provide a lifeline for the growth of programs (Olds, 2016). Policymakers should make policies that aim at preventing crimes in government departments to help in identifying incentives. Government organizations implement procedures for the success of department strategies. An organization will never understand whether a procedure needs to be changed unless they have the process for policy evaluation. Implementation and evaluation of systems create a safe, inclusive, and enjoyable working environment. Role of Criminological Theory in the Creation of Policy Criminologists study data and come up with theories on how to deter crime based on the conclusion of researched data. They advise policymakers on the methods of implementing approaches to public policy. Lawmakers put the opinions formed by criminologists into practice. For example, choice theory consists of four base theories with different policy implications, including deterrence, incapacitation theory, rational theory, and specific deterrence. The Roles of the Legislative, Executive, and Judicial Branches of Government in Shaping Crime Policy. The executive implements and oversees public policy endorsed by the legislature. The legislative arm of the government passes laws of the state and arrogates funds needed to control the government and crime policy implementation. The judiciary interprets the U.S constitution and applies law interpretation to the citizens. The division of power and responsibilities ensures that each branch exercises its function.
