Prosecutors' offices were identified from the National District Attorney's Association (NDAA) 2007 directory. This information was cross-referenced with previous contact lists and updated as necessary. The administration of the questionnaire included mailing out a hard-copy of the instrument, intensive multi-modal non-response follow-ups, and follow-up on surveys with missing or inconsistent responses. To ensure a high response rate, a web survey was designed to allow for multiple modes of disseminating and returning the survey. Questionnaires were received from 95% of the prosecutors offices.
