This study examines the effects (especially on violent and drug-trafficking crimes) of the bans on the manufacture, transfer, and possession of designated semiautomatic assault weapons and large capacity ammunition magazines under the Violent Crime Control and Law Enforcement Act of 1994. The analysis considers potential ban effects on primary and secondary gun markets, on assault weapons' uses in crime, and on the lethal consequences of assault weapons' use.

In the continuing effort to improve human service programs, funders, policymakers, and service providers are increasingly recognizing the importance of rigorous program evaluations. This report lays out the basic principles of program evaluation design. It signals common pitfalls, identifies constraints that need to be considered, and presents ideas for solving potential problems. These principles are general and can be applied to a wide range of human services programs.
