Byers v. Painter (4th Cir. 2026) Citation: No. 25-1058 (4th Cir. Apr. 17, 2026) TL;DR Holding: Officer not entitled to qualified immunity at motion-to-dismiss stage for fatal shooting of armed but non-threatening suspect. Why it matters: Reinforces that possession of a weapon + noncompliance ≠ automatic deadly force—there must be a real, immediate threat. Key limit: Case is at the pleading stage—facts are viewed in plaintiff’s favor, and video must clearly contradict them to

District of Columbia v. R.W. (2026) Citation: 608 U.S. ____ (2026) TL;DR Holding: Officers had reasonable suspicion to stop a driver where (1) a dispatch reported a suspicious vehicle, (2) passengers fled upon police arrival, and (3) the driver immediately attempted to leave with a door still open. Why it matters: The Supreme Court reinforces that courts must evaluate reasonable suspicion using the totality of the circumstances—not by isolating and discarding individual facts

Alexander v. Arceneaux , No. 25-30016 (5th Cir. Apr. 13, 2026) TL;DR Holding:  Officers did not  violate the Fourth Amendment when they seized electronics and appliances not listed in a firearm warrant because the items were lawfully seized under the plain view doctrine . Why it matters:  This case reinforces that plain view is driven by probable cause—not certainty . Officers can seize unlisted items if the totality of circumstances makes it reasonably apparent they are cont

State v. Porter, No. 24–1254 (Iowa 2026)  TL;DR The Iowa Supreme Court held that officers executing a premises search warrant  can search a visitor’s backpack if it is not in the person’s physical possession  and could contain the items listed in the warrant. The court rejected arguments based on privacy and abandonment, emphasizing that the case is about scope of the warrant—not whether a warrant was needed . Why it matters: Containers on scene = searchable if they can hold

United States v. Weaver (5th Cir. 2026)   TL;DR The Fifth Circuit reversed suppression of evidence from a search warrant supported by controlled buys, holding the affidavit was not “bare bones” and officers relied on it in good faith. The court also held that although the suspect’s written Miranda waiver was invalid due to deception , the district court failed to analyze whether the suspect implicitly waived his rights —so the case was remanded. Why it matters: Controlled buy

Citation:   Zorn v. Linton , 607 U.S. ___ (2026) Court:  United States Supreme Court Decision Date:  March 23, 2026 TL;DR Holding:  Officer entitled to qualified immunity; no clearly established law prohibited using a wristlock to lift a noncompliant protester after warnings. Why it matters:  Reinforces that excessive force claims fail unless prior case law matches the specific facts  closely. Key limit:  The Court did not  say the force was constitutional—only that it wasn’t

United States v. Parlin No. 24-1297 (1st Cir. Mar. 11, 2026)   TL;DR Holding:  Even if a police officer’s testimony about “user vs. dealer quantities” was improperly admitted, the conviction stands because the error was harmless  given overwhelming independent evidence of drug distribution. Why it matters:  Appellate courts will uphold convictions when bad evidence is merely “frosting”—not the “cake.” Limit:  Improper opinion testimony can still matter—but not when wiretaps,

United States v. Ponce No. 24-40632 (5th Cir. Mar. 9, 2026)   TL;DR Holding:  Border Patrol lawfully searched a vehicle at a checkpoint where initial consent allowed a visual inspection, and observations during that look created probable cause  to search a container (speaker box). Why it matters:  Even limited consent (just a “look”) can escalate into a full vehicle search  if officers develop probable cause based on what they see. Limit:  Consent scope still matters—but once

Law enforcement officers across the country are increasingly encountering individuals in severe behavioral crises. What was once commonly labeled “excited delirium” has evolved into a broader and more medically grounded understanding now referred to as Acute Behavioral Emergency (ABE) . The terminology has changed—but more importantly, so has the science, the legal landscape, and the expectations placed on officers. If your agency has not recently updated its policy or traini

United States v. Jones Citation:  United States v. Jones, No. 24-4282, ___ F.4th ___ (4th Cir. Feb. 4, 2026) TL;DR The Fourth Circuit affirmed Lawrence Jones’s firearm convictions, holding that sufficient circumstantial evidence supported a finding of constructive possession of firearms discovered inside a drug stash house. Even without fingerprints, eyewitness testimony, or exclusive control of the premises, the totality of the evidence allowed the jury to reasonably conclud

United States v. Erving Nos. 23-2828 & 23-2831 (7th Cir. Jan. 20, 2026) TL;DR The Seventh Circuit upheld a vehicle protective search  under Michigan v. Long  where a lone officer, late at night, observed furtive movements suggesting concealment, smelled burnt cannabis, learned the driver was on supervised release for a weapons offense, and reasonably believed the suspect could soon regain access to the vehicle. The court reaffirmed that reasonable suspicion—not probable cause

Title & Citation Case v. Montana , 607 U.S. ___ (2026)  (U.S. Supreme Court, Jan. 14, 2026). TL;DR Police can enter a home without a warrant  to render emergency aid when they have an objectively reasonable basis  to believe someone inside is seriously injured or imminently threatened with serious injury —and the Court refused to “upgrade” that standard into probable cause  just because the entry is into a home. Here, the officers reasonably believed Case had shot himself or

State v. Gerald Manchip White, 2024-K-01588 (La. Dec. 11, 2025) Holding:  The Louisiana Supreme Court reversed all convictions against a felon accused of possessing firearms found in a family home. The State failed to prove he exercised dominion and control  over the guns or had the intent  to possess them. Mere presence, awareness, or living in a home where others lawfully keep guns is not enough for a criminal conviction. Importance:  Officers frequently encounter multi-occ

Police officers routinely face one of the hardest judgment calls in criminal enforcement: Does what I’m seeing amount to mere suspicion, or does it rise to probable cause or proof of possession? Two recent appellate decisions — State v. Matt  (Montana 2025) and Moody v. State  (Mississippi 2025) — offer a powerful, real-world contrast that every patrol officer, interdiction unit, and investigator can learn from. One conviction was reversed  because the evidence never crossed

In law enforcement, we rely heavily on confidential informants. Many times, they’re the difference between having a good hunch and having actual probable cause. But the Seventh Circuit’s decision in United States v. Felton (2025)  gives us an important reminder: if your warrant affidavit leans on an informant, you must tell the judge the whole story — not just the parts that help you. This case walks through what happens when officers omit key credibility details , fail to co

Cases Compared: State v. Nagle , No. A23-0927 (Minn. Oct. 22, 2025) United States v. Long , No. 24-3377 (6th Cir. Oct. 17, 2025) TL;DR Holding (Nagle):  Minnesota’s high court suppressed evidence from a home search based solely on an uncorroborated informant tip. Holding (Long):  The Sixth Circuit upheld a home search based on a pattern of corroborated surveillance and drug activity. Importance:  These two cases, decided just days apart, show the razor-thin line between pro

In this week’s police training case brief, the Texas Court of Criminal Appeals tackled a question straight out of the patrol car: What happens when a K-9’s nose crosses the window line? In State v. Organ (Oct. 30, 2025), the state’s highest criminal court ruled that when a drug-detection dog’s nose enters a vehicle during a free-air sniff, that action becomes a Fourth Amendment search — one that requires probable cause. The decision draws a sharp boundary for handlers and hig

A Common Stop Gets a Legal Reality Check If you’ve spent any time behind the wheel of a patrol car, you’ve probably noticed it — license plate frames that cover part of a plate’s border, sometimes even the state name. Maybe it’s a dealer frame, maybe it’s a sports team. Many officers have pulled over cars for that kind of obstruction, figuring it’s a technical violation under state plate-display laws. But in October 2025 , the Kansas Supreme Court  handed down a ruling that s
