What is the definition of Source of Information (SOI)?

The correct definition of Source of Information (SOI) refers to a person who provides voluntary information for investigations. This encompasses individuals who may come forward with tips, insights, or details that could aid law enforcement in solving a case or understanding a situation better.

An SOI does not necessarily have to be a formal witness or involved in the crime; they can simply be an observer or someone with relevant information who offers their knowledge without being compelled to do so. This voluntary aspect is crucial, as it indicates that the information is given willingly, which can sometimes be valuable in gathering intelligence during an investigation.

Other options reflect different roles or types of individuals within law enforcement and the legal process but do not capture the essence of what constitutes a Source of Information. For instance, reporting crimes anonymously pertains to maintaining the identity of the reporter rather than focusing on the voluntary nature of the information shared. Key witnesses have a more formal role in legal proceedings, often testifying under oath, while a detective is someone actively involved in collecting evidence rather than simply providing information.
