889 (1968) (stating that courts look to “whether the officer’s action was justified at its inception” in determining the reasonableness of his actions). The Supreme Court has stated, “Only when the officer, by means of physical force or show of authority, has in some way restrained the liberty of a citizen may we conclude that a ‘seizure’ has occurred.” Id. at 19 n. 16, 88 S.Ct. 1868. Absent physical force, a seizure requires submission to a show of authority. California v. Hodari D., 499 U.S. 621, 626, 111 S.Ct. 1547, 113 L.Ed.2d 690 (1991). Petitioner was not yet seized when he saw officers approaching his vehicle with their guns drawn because he did not submit to their show of authority; rather, he jumped out of his vehicle and began walking away. See United States v. Smith, 594 F.3d 530, 539 (6th Cir.2010) (holding that defendant was not seized when he attempted to pass by officers in an apartment entryway because he did not “submit to [officers’] show of authority but, instead, tried throughout the encounter to push past the officers”); cf. United States v. Johnson, 620 F.3d 685, 691 (6th Cir.2010) (holding that defendant was seized when he stopped after being ordered to stop by police). Once Deputy Kozlowski grabbed him, Petitioner was unquestionably seized. See Hodari D., 499 U.S. at 629, 111 S.Ct. 1547 (finding that Hodari was not seized until he was tackled because he did not comply with an officer’s injunction to halt). Up to the point of seizure, then, the officers were acting on the basis of the information in the 911 call and Petitioner’s conduct as they approached the vehicle.
4. Reasonable Suspicion for a Stop
We agree with the district court’s determination that the 911 call and Petitioner’s evasive conduct gave rise to reasonable suspicion that Petitioner was involved in a shooting, justifying an investigatory stop. We start with the general rule that a police officer may conduct an investigatory stop if he has a “reasonable, articulable suspicion that the person has been, is, or is about to be engaged in criminal activity.” United States v. Place, 462 U.S. 696, 702, 103 S.Ct. 2637, 77 L.Ed.2d 110 (1983) (citing Terry, 392 U.S. at 22, 88 S.Ct. 1868). It is not enough to have “an inchoate and unparticularized suspicion or ‘hunch,’ ” Terry, 392 U.S. at 27, 88 S.Ct. 1868, but “the level of suspicion required for a Terry stop is obviously less demanding than for probable cause,” Alabama v. White, 496 U.S. 325, 330, 110 S.Ct. 2412, 110 L.Ed.2d 301 (1990) (quoting United States v. Sokolow, 490 U.S. 1, 7, 109 S.Ct. 1581, 104 L.Ed.2d 1 (1989)).
Where an informant tip, rather than police observation, is the basis of an investigatory stop, the tip must exhibit “sufficient indicia of reliability to provide reasonable suspicion to make the investigatory stop.” Florida v. J.L., 529 U.S. 266, 270, 120 S.Ct. 1375, 146 L.Ed.2d 254 (2000) (quoting White, 496 U.S. at 327, 110 S.Ct. 2412). The tip is evaluated under a “totality of the circumstances” standard. Illinois v. Gates, 462 U.S. 213, 231, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983) (evaluating whether anonymous informant tip gave rise to probable cause); White, 496 U.S. at 328-29, 110 S.Ct. 2412 (applying Gates’ totality of the circumstances standard to determine if anonymous tip gave rise to reasonable suspicion). An informant’s veracity, reliability, and basis of knowledge are highly relevant to the analysis. Gates, 462 U.S. at 231, 103 S.Ct. 2317. Where a tip cannot be verified because it is anonymous, the Supreme Court recognizes the probative value of “corroboration of details of an informant’s tip by independent police work.” Id. at 241, 103 S.Ct. 2317.
