%0 Journal Article %T Policy Gridlock versus Policy Shift in Gun Politics: A Comparative Veto Player Analysis of Gun Control Policies in the United States and Canada %A Charles Burton %A Rifat Darina Kamal %J World Affairs %@ 1940-1582 %D 2018 %R 10.1177/0043820018814356 %X Why do major events of gun violence (i.e., mass shootings) lead to incremental change or no federal legislative change at all in the United States while major events of gun violence have resulted in large-scale legislative changes in Canada? Exploring the complexities involved in this compelling question, this article conducts a comparative analysis of recent gun control policy gridlock and shift in these two countries. We concentrate on two mass shooting cases in each country: the Columbine (1990) and Sandy Hook (2012) massacres in the United States and the école Polytechnique Massacre (1989) and Concordia Shooting (1992) in Canada. We use veto player theory to gain insights into why tightening gun policy is so difficult to implement in the United States while Canada often follows up with policy transformations after a focusing event. This theory informs the central argument that the key factors underpinning the divergent policy outcomes on gun control issues in both countries involve differences in the structure of government/institutional design and the role and power of interest groups in each case %K Gun Control %K Firearms Restrictions %K Gun Violence %K Mass Shootings %K Regulation Policy %K Interest Groups %K Comparative Public Policy %K Institutional Design %K Veto Player Theory %K Canada %K United States %K National Rifle Association %K Coalition for Gun Control. %K Política Pública Comparativa %K Control de Armas %K Grupos de Interés %K Ajustes Institucionales %K Teoría de Veto Player %K Canadá %K EE.
