During a routine driver's-license checkpoint in Fort Worth, Officer Tom Maples stopped Clifford Brown's car. While standing outside the driver's-side window, Maples shone a flashlight into the car and saw Brown remove a knotted, opaque green party balloon from his pocket and drop it beside the seat. Maples knew from narcotics arrests that drugs were often packaged in tied-off balloons.
Maples shifted his position to look into Brown's open glove compartment. There he saw small plastic vials, loose white powder, and a bag of party balloons. After Brown said he had no driver's license, Maples directed him out of the car, picked up the balloon, and saw what appeared to be powder inside its tied-off end. Officers then arrested Brown and later found additional suspected drug-related items. Testing established that the balloon contained heroin.
Brown was convicted of heroin possession. The Texas Court of Criminal Appeals reversed, holding that the balloon should have been suppressed. Relying on the plain-view doctrine as described in Coolidge v. New Hampshire, it reasoned that the balloon's incriminating nature was not "immediately apparent" because the officer did not know it contained contraband when he seized it. The Supreme Court granted certiorari and reversed.
Issue #1
Whether the Supreme Court had jurisdiction when Brown argued that the Texas decision rested on an independent and adequate state-law ground.
Holding
Yes. The Texas Court of Criminal Appeals rested its decision on federal Fourth Amendment law, not an independent state-law ground.
Reasoning
Although Brown invoked the Texas Constitution, the state court's analysis depended squarely on its understanding of the federal Fourth Amendment and the Supreme Court's plurality opinion in Coolidge. Its cited Texas decisions likewise applied Coolidge rather than independent state constitutional doctrine. The Supreme Court therefore could review the federal question.
Issue #2
Whether Officer Maples' observation of the car's interior and open glove compartment was a Fourth Amendment search that invalidated reliance on plain view.
Holding
No. The officer lawfully observed what was visible from outside the vehicle, and use of a flashlight and a changed viewing angle did not create a Fourth Amendment search.
Reasoning
The driver's-license checkpoint was a valid stop, and Maples was lawfully positioned beside Brown's vehicle. Illuminating the interior with a flashlight did not invade any protected privacy interest; it merely made visible what darkness otherwise obscured.
Maples also could change his position and look through the car windows. Brown had no legitimate expectation of privacy in portions of the automobile interior that passersby or police officers could see from outside. Thus, the observations that supplied the basis for seizure were lawfully made.
Issue #3
Whether the plain-view doctrine permitted the warrantless seizure of the opaque, tied-off balloon when the officer could not see its contents.
Holding
Yes. A plain-view seizure requires probable cause to associate the object with criminal activity, not near certainty or actual knowledge that it is contraband.
Reasoning
Plain view is better understood as an extension of a lawful prior justification for an officer's access to an object, rather than as a freestanding exception to the warrant requirement. When an officer lawfully sees an item and has probable cause to connect it to criminal activity, seizing it ordinarily causes no additional invasion of privacy and is reasonable under the Fourth Amendment.
The phrase "immediately apparent" from the Coolidge plurality does not require an officer to know with certainty that an item is incriminating. Probable cause is a practical, nontechnical probability, based on the facts known to a trained officer, that the object may be contraband, stolen property, or evidence of crime.
Maples had probable cause here. His experience taught him that narcotics were frequently carried in balloons tied in the particular manner Brown used. The loose white powder, small vials, and bag of balloons in the open glove compartment reinforced the inference that Brown possessed drugs. The balloon's opaque character did not defeat probable cause because its distinctive form and context were themselves highly incriminating.
Issue #4
Whether the Coolidge inadvertence requirement barred the seizure because officers operating the checkpoint generally expected that some stopped vehicles might contain narcotics.
Holding
No. Even assuming an inadvertence requirement applies, the seizure was inadvertent on these facts.
Reasoning
The Court did not decide the ultimate status of inadvertence as an element of plain view. It held only that the requirement posed no obstacle in this case because the checkpoint was not shown to be a pretext for searching Brown's car for drugs.
The officers' generalized expectation that some cars in an area with moderate narcotics traffic might contain drugs did not establish prior knowledge of evidence in Brown's particular car. Maples had no reason to expect that Brown possessed the balloon or that any specific incriminating object would be in the glove compartment.
