This study was designed to clarify the status of stalking laws and their implementation needs. To accomplish this, the principal investigator conducted a survey of police and prosecutor agencies across the country to determine how stalking laws were being implemented. While there had been significant federal support for state and local agencies to adopt anti-stalking laws and implement anti-stalking initiatives, no comprehensive review of the status of such efforts had been done. Thus, there had been no way of knowing what additional measures might be needed to enhance local anti-stalking efforts. Two national surveys on stalking were conducted. The first survey of 204 law enforcement agencies (Part 1, Initial Law Enforcement Survey Data) and 222 prosecution offices (Part 3, Initial Prosecutor Survey Data) in jurisdictions with populations over 250,000 was conducted by mail in November of 1998. The survey briefly asked what special efforts the agencies had undertaken against stalking, including special units, training, or written policies and procedures. A replication of the first national survey was conducted in November of 2000. Part 2, Follow-Up Law Enforcement Survey Data, contains the follow-up data for law enforcement agencies and Part 4, Follow-Up Prosecutor Survey Data, contains the second survey data for prosecutors. Parts 1 to 4 include variables about the unit that handled stalking cases, types of stalking training provided, written policies on stalking cases, and whether statistics were collected on stalking and harassment. Parts 2 and 4 also include variables about the type of funding received by agencies. Part 4 also contains variables about other charges that might be filed in stalking cases, such as harassment, threats, criminal trespass, and protection order violation.
