Accordingly, a general suspicion or a mere hunch is not sufficient to support an investigative stop. Although the primary means by which DUI police officers acquire reasonable suspicion is a personal observation of DUI driving, information acquired from an informant that exhibits a sufficient indicia of reliability can also be the basis for reasonable suspicion in a DUI investigation. Alabama v. White, 496 U.S. 325, 328, 110 S.Ct. 2412, 110 L.Ed.2d 301 (1990). Where the information is provided to police by an informant who is either an identified interested citizen or an identified victim of a crime, there is a presumption of reliability. Hinson v. State, 229 Ga.App. 840, 842, 494 S.E.2d 693 (1997); Hudson v. State, 253 Ga.App. 210, 211, 558 S.E.2d 420 (2001). But where police acquire information from an anonymous informant or one of unknown reliability, this is ordinarily not a sufficient basis to provide reasonable suspicion, unless the information exhibits sufficient indicia of reliability.
Alabama v. White, 496 U.S. at 329-332, 110 S.Ct. 2412; Florida v. J. L., 529 U.S. 266, 269-271, 120 S.Ct. 1375, 146 L.Ed.2d 254 (2000). For example, the information provided by these types of informants may exhibit sufficient indicia of reliability if it provides details correctly predicting a subject’s “not easily predicted” future behavior, or if it provides other details that police corroborate as showing similar inside information about the subject’s affairs. Alabama v. White, 496 U.S. at 332, 110 S.Ct. 2412; Britton v. State, 220 Ga.App. 120, 121-122, 469 S.E.2d 272 (1996).
