Thirty-nine categories are grouped into nine major sections: Law Enforcement, Prosecution and Defense, Courts, Probation, Youth, Corrections, Parole, Associations, and State Level Criminal Justice Agencies. Sheriffs Departments are listed in the Law Enforcement category even though most also operate correctional facilities at the county level. Within categories, agencies are listed alphabetically by county, agency, region, or person where appropriate; State Police Troop Headquarters are listed alphabetically by the troop letter designation. Law enforcement agencies listed in the directory are departments that report offense and arrest information to the Division of Criminal Justice Services under the Uniform Crime Reporting or New York State Incident Based Reporting programs. These departments consist of police officers or, in the case of land grant colleges, peace officers and/or private security staff. Basic requirements for reporting to the Division of Criminal Justice Services are a defined jurisdiction of patrol, jurisdiction covering criminal offenses, and access to a New York State Police Information Network computer terminal.
