Does Floyd have a reasonable suspicion to justify an investigatory stop?

Whether law enforcement officers had a reasonable suspicion to justify an investigatory stop of Floyd is a mixed question of law and fact that we review de novo. United State v. Hernandez-Alvarado, 891 F.2d 1414, 1416 (9th Cir.1989). An officer may make such a stop if he is aware of specific, articulable facts that, taken with objective and reasonable inferences, form a basis for suspecting that the particular person detained is engaged in criminal activity.
