Summary

This data collection examines the impact of the Supreme Court decision in "UNITED STATES VS. LEON" on police search warrant applications in seven jurisdictions. For this collection, which is one of the few data collections currently available for the study of warrant activities, data were gathered from search warrant applications filed during a three-month period before the Leon decision and three months after it. Each warrant application can be tracked through the criminal justice system to its disposition. The file contains variables on the contents of the warrant such as rank of applicant, specific area of search, offense type, material sought, basis of evidence, status of informants, and reference to good faith. Additional variables concern the results of the warrant application and include items such as materials seized, arrest made, cases charged by prosecutor, type of attorney, whether a motion to suppress the warrant was filed, outcomes of motions, appeal status, and number of arrestees.
