Which type of investigation rarely requires surveillance?

Accounting/Financial fraud investigations typically rely on analyzing documents, records, and data rather than physical surveillance. In these cases, auditors and investigators examine financial statements, transaction histories, and other business records to identify irregularities or discrepancies that may indicate fraudulent activities. The focus is on gathering forensic evidence from existing documentation rather than observing individuals or actions in real-time.

In contrast, investigations related to criminal assault or drug trafficking often involve surveillance to gather evidence regarding suspects’ movements or behaviors, as these offenses frequently require firsthand observations to build a case. Case management files also do not inherently require surveillance, but they may involve tracking progress or outcomes over time rather than monitoring individuals directly.
