Not every case in this brief applies nationwide. Only decisions from the Supreme Court of the United States are binding across all states. Federal circuit court rulings apply within their specific regions, and state court decisions apply only within that state. However, all of these cases are still valuable for training purposes, they reflect how courts are currently evaluating officer actions and often signal where the law is heading.
Can officers order someone out of a home during a gun call without probable cause or exigent circumstances?
PEOPLE v. PEREZ
Issue: Seizure at a residence without a warrant
Court: California Court of Appeal
State: California
-
Late at night, officers responded to a report of a man walking through a high-crime area while armed with a gun. Shortly afterward, a second caller reported that the man had placed the gun inside a white Kia parked nearby. One of the officers then realized he had recently seen a man matching that description (later identified as defendant Ulises Perez) near a Kia and had watched him enter a nearby apartment.
Without obtaining a warrant or establishing exigent circumstances, officers approached the apartment and saw Perez inside through a screen door. Standing outside, they drew their weapons and ordered him to come out. After a brief delay, Perez complied and was detained. A witness later identified him, and officers recovered a firearm and narcotics from the nearby vehicle and from his person. Perez moved to suppress this evidence, arguing that he had been unlawfully seized while still inside his home.
Answer: NO
The court held that ordering someone out of a residence, by means of a show of authority, constitutes a seizure within the home. Such a seizure requires probable cause and either a warrant or exigent circumstances. Without those, the seizure is unconstitutional, and the evidence may be suppressed.
Takeaway: That command “Come out” = a seizure inside the home > requires probable cause + warrant or exigency. You cannot bypass this by staying outside.
Does using public Wi-Fi allow police to monitor someone’s internet activity without a warrant?
STATE v. De Witt SIMONS
Issue: Digital surveillance / privacy
Court: Oregon Supreme Court
State: Oregon
-
A business owner running a public Wi-Fi network noticed suspicious activity and contacted law enforcement. Officers instructed the owner to help monitor the user’s internet activity.
Over the course of about a year, the business tracked and recorded the suspect’s browsing behavior, logging more than 255,000 webpage visits and collecting packet capture data, all without a warrant.
Using this data, law enforcement identified the defendant, arrested him, and secured a conviction on a charge of encouraging child sexual abuse.
The defendant later challenged the surveillance as an unlawful search.
Answer: NO
The Oregon Supreme Court ruled that police cannot rely solely on a person’s use of public Wi-Fi to justify prolonged, warrantless monitoring of that person’s internet activity. Here, law enforcement enlisted a business owner and a consultant to monitor and log the defendant’s browsing activity for roughly a year. The lower courts concluded that the defendant had no protected privacy interest because he used a public network and accepted the terms of service.
The Oregon Supreme Court disagreed, holding that individuals retain a privacy interest in their internet browsing history even on public networks, and that monitoring the defendant’s activity for a year constituted a search under the Oregon Constitution. Because the State failed to justify conducting the search without a warrant, the court reversed the lower courts’ decisions and remanded the case.
Takeaway: That level of monitoring = a search > warrant required.
Digital investigations are being treated like physical searches
Long-term monitoring = warrant territory
When does questioning a juvenile at school become a custodial interrogation?
STATE v. K.R.C.
Issue: Custody / Miranda (juveniles)
Court: Idaho Supreme Court
State: Idaho
-
The day after he was accused of inappropriate touching at school, a 12-year-old student was removed from class and taken to a small, closed office.
One officer questioned him while another stood near the door.
He was not given Miranda warnings or told that he could leave, refuse to answer questions, or contact his parents.
During that interview, he admitted he might have accidentally touched another student.
Less than an hour later, he was questioned again in a different room, this time in front of multiple authority figures, including officers and school staff. During this second round of questioning, he made additional incriminating statements.
Answer: YES
Yes. The Wisconsin Supreme Court held that the student was in custody for Miranda purposes during both school interviews, even though the questioning took place at school rather than at a police station. In reaching this conclusion, the Court emphasized several factors: the student’s age; that officers removed him from class; that he was questioned behind closed doors; that he was surrounded by authority figures; and that he was never told he was free to leave or to refuse to answer questions.
Given these circumstances, Miranda warnings were required before questioning. Because no warnings were given, his statements should not have been admitted. Nonetheless, the Court declined to overturn the delinquency adjudication, finding the error harmless in light of the other evidence presented.
Takeaway: This was a custodial interrogation = statements suppressed. “Not under arrest” doesn’t matter; the environment is what controls the situation.
If a stop turns into an unlawful arrest, can the evidence still be used?
STATE v. CAMPBELL
Issue: Custody / Miranda (juveniles)
Court: Idaho Supreme Court
State: Idaho
-
While investigating a stolen motorcycle, a trooper saw two individuals standing near motorcycles with no license plates. One of the motorcycles appeared to match a recently stolen vehicle and appeared to have been freshly spray-painted. The trooper later encountered the same two individuals inside a convenience store.
Before fully confirming the circumstances, the trooper ordered both individuals to the ground and placed them in handcuffs. A court later ruled that this conduct constituted an unlawful arrest.
After learning that one of the individuals was on felony probation, the trooper contacted a probation officer, who authorized a search. Officers conducting that search found drugs and paraphernalia.
Answer: YES
Only because the Court concluded that the evidence would have been discovered through lawful means anyway. The Idaho Supreme Court held that the initial handcuffing amounted to an unlawful arrest and rejected the argument that officer safety justified it in these circumstances.
Even so, the Court admitted the evidence, reasoning that officers would inevitably have found it in the normal course of the investigation. The crucial distinction is that the stop itself was not upheld; the evidence survived solely because the Court identified an independent lawful route that would have led to the same outcome.
Takeaway: Evidence allowed under inevitable discovery. Bad stops don’t automatically kill cases, BUT:
Courts will analyze what would’ve happened anyway
Proactive stops
Detention vs arrest decisions
If officers have probable cause for any offense, does that defeat a false arrest claim?
THOMAS v. McAULIFFE
Issue: Probable cause / false arrest
Court: U.S. Court of Appeals for the Seventh Circuit
State(s): Illinois, Indiana, Wisconsin
-
Traffic stop > odor of marijuana removal > search > arrest > Suspect sued.
Officers initiated a traffic stop after observing the driver fail to signal. As they approached, they reported detecting the odor of marijuana. The driver partially complied by rolling down his window but did not fully follow subsequent commands.
Officers then opened the vehicle door, removed the driver, and placed him in handcuffs. A subsequent search of the vehicle resulted in the discovery of marijuana and related paraphernalia. Although Thomas denied ownership of the items, he was cited for the traffic violation and possession of marijuana. He later filed a civil lawsuit alleging the stop and arrest were unlawful.
Answer: YES
In this case, the Seventh Circuit reaffirmed that when officers have probable cause to arrest for any offense, a false arrest claim cannot succeed, even if the plaintiff later challenges other aspects of the encounter. The appellate court upheld the verdict in favor of the officers, found no basis to disturb it, and rejected arguments that the jury was misled by the instructions or by the officer’s testimony.
Takeaway: If probable cause exists for at least one arrestable offense, it remains a strong legal defense to a false arrest claim.
PC = The Shield
Even minor violations can justify enforcement, which is especially important in the context of traffic stops, vehicle searches, and arrest situations.
Does a probation search condition allow officers to search everything on a phone?
MEINER v. SUPERIOR COURT
Issue: Illegal detention = evidence admissibility
Court: California Court of Appeal
State: California
-
Officers searched the probationer’s phone and Apple Pay despite an explicit restriction on accessing financial data.
The probationer was suspected of diverting funds from his employer. Under his probation terms, he had agreed to warrantless searches of his electronic devices, but the conditions specifically excluded searches of his financial accounts or transactions.
After his arrest, officers seized his phone and searched it, accessing Apple Pay and other financial apps. The search revealed linked bank accounts, which in turn supported a warrant and produced additional evidence.
The defendant later moved to suppress the evidence, arguing that the search of financial applications exceeded the scope of the probation condition.
Answer: NO
The California Court of Appeal held that officers exceeded the scope of a probation search when they accessed Apple Pay and related financial data. The court concluded that Apple Pay constitutes a “financial account,” which the defendant’s probation conditions expressly excluded from search.
Because this initial search was unlawful, all information subsequently derived, including bank account records later obtained by warrant, was tainted. Accordingly, the court suppressed the evidence.
Takeaway: search authority is confined to the precise terms granted, and overstepping those limits can invalidate all evidence subsequently obtained.
Search exceeded scope = evidence suppressed.
“Searchable” doesn’t mean everything is searchable
Phone’s ≠ unlimited access
