The usage of CVSA is similar to Polygraph.  Both of these applications are tools utilized to gain information based on facts. They are used in private industry and many law enforcement applications. The key is training and later obtaining a higher skill level which would be obtained through experience.. I feel essential elements are, having good investigative skills and interrogation abilities. Again they are only tools, the methods are not absolute. Another key element is proper training,regulation and standards. In closing I feel over the years, Polygraph in our state has been regulated to a high standard. CVSA should be regulated in the same manner. Also maintaining a open communication with the public and individuals utilizing the method.  Att: Marjorie King, Executive Director
