952 F.3d 876
7th Cir.2020Background
- ShotSpotter detected gunfire at ~4:40 a.m. on the 2200 block of North Ellis Street; two alerts were received and dispatcher broadcast corroborating 911 reports that cars were leaving and a man ran northbound.
- Officer Ellefritz responded, arrived ~5½ minutes after the initial alert, and saw a single vehicle leaving the block; he activated lights and ordered it to stop.
- Occupants yelled toward the dead-end crowd; the passenger (Terrill Rickmon) later said he had been shot in the leg; a consensual search of the car after backup found a 9mm handgun under the passenger seat.
- Rickmon, a felon, was indicted under 18 U.S.C. § 922(g)(1) and moved to suppress the firearm, arguing ShotSpotter and the stop were unreliable and constitutionally unjustified.
- The district court denied suppression; the Seventh Circuit affirmed, holding the stop was supported by reasonable suspicion based on the totality of circumstances (ShotSpotter + corroborating dispatch/911 reports, proximity, time, lone vehicle, officer experience).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Officer had reasonable suspicion to stop a vehicle leaving the ShotSpotter area | Rickmon: A ShotSpotter alert and mere emergence from the area are insufficient; proximity alone cannot transfer suspicion to occupants | Government: Totality (two ShotSpotter alerts, corroborating 911/dispatch reports, temporal/physical proximity, lone vehicle at 4:45 a.m., officer experience) produced reasonable suspicion | Stop was reasonable under the totality of the circumstances and suppression denial affirmed |
| Whether information known to dispatch but not conveyed to the officer can justify the stop | Rickmon: Officer cannot rely on information he did not have; uncommunicated 911 details cannot retroactively justify the stop | Government: Collective knowledge of the police/disptacher should be imputed to justify the stop | Court refused to rely on unbroadcast 911 information; actual knowledge of the stopping officer controls |
| Whether ShotSpotter standing alone is sufficiently reliable | Rickmon: ShotSpotter is an anonymous, possibly error-prone system and cannot alone furnish individualized suspicion | Government: ShotSpotter is analogous to an anonymous tip and may be relied on when corroborated by other reports | Court assumed ShotSpotter analogous to an anonymous tip but did not base the decision on ShotSpotter alone; corroboration by 911/dispatch made the stop reasonable |
