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.

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) .

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
