Random investigation is a term used to refer to a process of investigation that is not predetermined or selective, but is rather conducted in a haphazard or arbitrary manner. Synonyms for random investigation include unplanned search, casual inquiry, haphazard scrutiny, unsystematic examination, chance inspection, and ad hoc investigation. These terms all denote an investigative process that lacks a definitive plan or intention, but instead relies on the occurrence of opportunity or chance. Such investigations can be useful in discovering important information that may otherwise have gone unnoticed, but they can also be inefficient and time-consuming without a clear goal or objective.
