| Court: | US Supreme Court |
| Facts: | Wardlow is in a "high crime" area with an opaque bag. He takes off when he sees a caravan of cops. They frisk him and find a gun in the bag. Uh-oh, he's also a felon. |
| Posture: | The gun is admitted at trial, and then reversed on appeal. The state appeals from there. |
| Issue: | Was there sufficient reasonable suspicion to justify the stop and frisk? |
| Holding: | Yes. Reversed. |
| Rule: | The officer must be able to articulate more than an an inchoate and unparticularized suspicion or hunch of criminal activity. |
| Reasoning: | There was plenty of cause for suspicion here: the area and nervous evasive behavior were enough, but here we also had headlong flight. |
