# ALPR Alert Verification There is no single verification rule established here for every Arkansas agency. The applicable requirements come from source-specific regulations and local policies, while the Fourth Amendment asks whether the facts known to officers supported the stop and any force used. ## Source-specific requirements - **Arkansas State Police.** 12 CAR Part 24 requires ASP officers to verify the physical plate and issuing state, confirm status through communications or ACIC/NCIC, and make reasonable efforts to compare occupants with a wanted-person description before an alert-based stop. It is an ASP rule, not a statewide municipal policy. (primary public record, [12 CAR Part 24](../../web%20archive/2026-08-10/webftp.blr.arkansas.gov/12-car-part-24-license-plate-readers.md)) - **Sherwood.** Policy 11.08.00, adopted March 24, 2026, requires visual plate verification, ACIC/NCIC confirmation, and says an unverified hit may not be the sole stop basis ([[Sherwood ALPR Policy 11.08.00]], p. 3). It postdates the February 11 incident and is not proof of the policy then in force. - **Jacksonville.** Policy 10-28 requires visual verification of characters and issuing state plus a dispatch or MDT status check when circumstances allow, and calls for alert disposition recording ([[Jacksonville LPR Policy and Retention Settings]], p. 2). ## Stop gate *Kansas v. Glover* permits an owner-as-driver inference to support reasonable suspicion when nothing known negates it, but emphasizes that contrary facts can dispel the inference. *Porter* found a verified active-warrant ALPR hit sufficient on its ten-detection record. Neither creates a categorical hit-equals-stop rule. (primary public record, [Kansas v. Glover](../../web%20archive/2026-08-10/supremecourt.gov/kansas-v-glover-589-u-s-376-2020.md)); (primary public record, [United States v. Porter](../../web%20archive/2026-08-10/ca5.uscourts.gov/usa-v-porter-no-25-60163-5th-cir-mar-17-2026.md)) The Eighth Circuit upheld a stop on an ambiguous insurance-database return in *Mitchell*, but reliability and officer-competency arguments were waived and expressly left unresolved. *Williams* permits an objectively reasonable vehicle-identification mistake on combined facts; it does not decide an alert contradicted by an immediately visible physical plate. (primary public record, [United States v. Mitchell](../../web%20archive/2026-08-10/ecf.ca8.uscourts.gov/united-states-v-cedric-mitchell-no-25-1261-8th-cir-mar-31-2026.md)); (primary public record, [United States v. Williams](../../web%20archive/2026-08-10/ecf.ca8.uscourts.gov/united-states-v-devion-williams-929-f-3d-539-8th-cir-2019.md)) *Herring* concerns suppression and assumed rather than decided a Fourth Amendment violation; it held isolated negligent police database maintenance insufficient for exclusion while leaving deliberate, reckless, grossly negligent, or systemic error on a different footing. It does not decide private-vendor error. (primary public record, [Herring v. United States](../../web%20archive/2026-08-10/govinfo.gov/herring-v-united-states-555-u-s-135-2009.md)) ## Force and detention gate Weapons and handcuffs can remain within a *Terry* stop when particular danger, suspected weapon, duration, behavior, and scene-control facts justify them. *Bell*, *Pollreis*, and *Andre Johnson* apply that contextual rule. *El-Ghazzawy* supplies the limit: handcuffing a cooperative person without an objective safety concern or other legitimate need can be excessive and convert the stop into an arrest. (primary public record, [United States v. Bell](../../web%20archive/2026-08-10/ecf.ca8.uscourts.gov/united-states-v-clinton-bell-480-f-3d-860-8th-cir-2007.md)); (primary public record, [Pollreis v. Marzolf](../../web%20archive/2026-08-10/ecf.ca8.uscourts.gov/casondra-pollreis-v-lamont-marzolf-9-f-4th-737-8th-cir-2021.md)); (primary public record, [United States v. Andre Johnson](../../web%20archive/2026-08-10/ecf.ca8.uscourts.gov/united-states-v-andre-johnson-31-f-4th-618-8th-cir-2022.md)); (primary public record, [El-Ghazzawy v. Berthiaume](../../web%20archive/2026-08-10/ecf.ca8.uscourts.gov/el-ghazzawy-v-berthiaume-636-f-3d-452-8th-cir-2011.md)) ## Sherwood evidence boundary The Sherwood record shows that the OCR-generated plate returned a stolen record while the physical plate differed in its final character ([[Sherwood Incident and CAD Records]], p. 4). It does not establish every fact officers perceived, the policy in force, the timing of each verification step, what database information appeared, the occupant description, or the safety facts supporting force. The event is therefore a documented error-and-governance finding, not an adjudicated constitutional violation. Program accuracy should separate OCR, list freshness, human verification, occupant association, database return, stop basis, force, and outcome; see [[ALPR Error Layers and Outcome Measurement]].
