“…direct the Bureau of Justice Statistics to create a proposal for the development of a nationally representative survey to determine forensic capabilities for those who write reports and offer testimony within federal, state and local law-enforcement agencies and for medical examiner and coroner offices. The survey instrument should be developed in collaboration with the relevant stakeholders organizations...”
6
Measures to be addressed: 1. Types of forensic services provided; 2. Agency policies and procedures related to forensic evidence and processing, including certification and/or accreditation; 3. Staffing for forensic services and related functions; 4. Testimony in legal proceedings, including: a. Depositions; b. Interrogatories; c. Reports/analysis to the court; d. Sworn testimony in court.
7
Option 1: Utilize newly developed sample- based data collection vehicle a. Will yield results more quickly; b. Provides a broad understanding of the issues; c. Not suited to a detailed examination of the component topics. Expected timeframe for completion: December 2015* (contingent; subject to change)
8
The system is designed to: Conduct ongoing data collection from a nationally representative sample of law enforcement agencies; Field surveys that are short (approximately 30 questions; burden of 20 minutes or less) and provide findings within 6 months of initial survey administration; Collect and distribute information through an interactive website.
9
Option 2: Employ a 2-stage survey design methodology a. Establishes a set of measures on which to stratify agencies for the 2 nd stage survey; b. Can address concepts more comprehensively; c. Requires significantly greater resources to field, including additional funding; d. Results would not be realized for several years. Expected timeframe for completion: December 2018* (contingent; subject to change)
10
2-stage design: 1. Census of State and Local Law Enforcement Agencies (LE Census) – survey of all 20,000+ LE agencies in the United States Include 1 – 3 targeted questions to provide additional measures on which to stratify the sample of LEAs in the 2 nd stage survey 2. Law Enforcement Agency Forensic Services Survey (LEAFSS) – sample based survey format Stand-alone survey would ask questions specific to the various measures of importance to the NCFS
11
1. What is the goal of a survey of LEAs and the forensic services in which they engage? Enumeration of agencies providing services of any type? Of a specific type or types? Types of services in which LEAs engage? Does frequency matter? Establishing knowledge base regarding accreditation and/or certification? Establishing guidelines for those who write reports and offer testimony about forensic services in court?
12
2. What information is needed to assess the impact of establishing accreditation and/or certification standards for LEAs? Backlogs; Cost to agencies; Amount of staff time that would be devoted to the cert/accred process; Other information to help determine if processing burden will be shifted to state or other labs
