Summary: A science-based discussion of the issue of gun control in the United States. After reviewing some basic statistics about crime and gun ownership, I examine the empirical evidence concerning the relationship between gun ownership and violent crime, highlighting the many difficulties associated with such studies and the limitations of this literature. I then discuss some more specific aspects of the gun control debate, including the question of who commits most violent crimes, how deadly guns are compared to other weapons, and how criminals acquire guns. I conclude with a discussion of the evidence for and against various types of gun control measures, and some thoughts on contemporary US gun culture and its impact on gun policy.
