During an Investigation, a Lead Will Be Investigated If, and Only

During an investigation, a lead will be investigated if, and only if, it is deemed credible by a Special Agent. Leads will generally be considered credible when the information comes from a trusted source. To increase the chances of finding credible leads, some Special Agents spend time building relationships with informants. Informants are often useful in verifying information about suspects under investigation, such as the suspects' identities and addresses. If an informant provides accurate information about a lead, the chances of successful prosecution are increased.
