Plain Feel

Plain Feel

Plain view began as a rule about sight, and the discussion of Hicks showed where it stops: an officer who has to handle an object to learn what it is has not yet found anything whose character is apparent. The same logic extends to the other senses. Officers lawfully present in a place may use all of their senses there, so smell and hearing are analyzed along lines similar to those that govern vision.¹ Touch is the sense the Supreme Court took up in Minnesota v. Dickerson, which asked whether contraband felt during a protective pat-down may be seized without a warrant.² The analogy comes naturally once the reason for plain view is in hand. When contraband lies in open view and an officer sees it from a lawful vantage point, no legitimate expectation of privacy has been invaded, so there is no search apart from the intrusion that put the officer there. Requiring a trip to a magistrate would also usually be impracticable and would do little for the interests the Fourth Amendment protects.³

The facts begin with a stop the officers had reason to make. On the evening of November 9, 1989, two Minneapolis officers on patrol saw Dickerson leave a 12-unit apartment building that one of them regarded as a notorious crack house, having answered complaints of drug sales in its hallways and executed several search warrants there.⁴ When Dickerson noticed the squad car and made eye contact with an officer, he stopped and walked the other way, then turned into an alley beside the building. The officers took that apparent evasion, together with his departure from a building known for cocaine traffic, as grounds to stop him, and they pulled into the alley and ordered him to submit to a pat-down.⁵ The pat-down revealed no weapons, but the officer took an interest in a small lump in the front pocket of Dickerson's nylon jacket. By the officer's account, he examined the lump with his fingers, it slid, and it felt like crack cocaine in cellophane. The officer then reached into the pocket and retrieved a small plastic bag holding one fifth of a gram of crack cocaine.⁶

Dickerson was charged with possession of a controlled substance and moved to suppress the cocaine. The trial court found the stop and the frisk justified under Terry v. Ohio, analogized to plain view, and refused to suppress. The Minnesota Court of Appeals reversed, declining to adopt a plain feel exception, and the Minnesota Supreme Court affirmed.⁷ Dickerson never challenged the finding that the stop and the frisk were justified, and the prerequisites for them are taught elsewhere: a stop on reasonable suspicion, and a protective frisk only when the officer also reasonably believes the person is armed and dangerous, with the frisk generally confined to a pat-down of outer clothing for concealed instruments of assault. Because those steps were settled, the Court could look only at what the officer did once the lump was felt. The dispositive question was whether the officer was acting within lawful bounds at the moment he gained probable cause to believe the lump was contraband.⁸

Dickerson answers that question in two holdings, and the next two sections take them in the order the Court did. The first holding is the analogy itself. If an officer lawfully pats down outer clothing and feels an object whose contour or mass makes its identity as contraband immediately apparent, no privacy has been invaded beyond what the weapons search already authorized, and the seizure rests on the same practical considerations as a plain-view seizure.⁹ The resulting plain feel doctrine permits seizure of what an officer can identify as incriminating by touch but not by manipulation.¹⁰ The second holding supplies the limit. A Terry pat-down exists to discover weapons, so once the officer concludes that an object is not a weapon, further manipulation of it has no justification left and turns the frisk into an evidentiary search, which makes the seizure unlawful.¹¹ The officer's description of examining the lump with his fingers after the frisk had found no weapon is what lets one case teach both halves: the doctrine reaches what touch alone reveals, and the cocaine was suppressed because the officer's further examination went beyond what the weapons search allowed. The first holding, which carries plain view from sight to touch, comes next.

Plain View by Touch

Plain view permits a warrantless seizure when the officer is lawfully in a position from which the object is seen, its incriminating character is immediately apparent, and the officer has a lawful right of access to it.¹² In Minnesota v. Dickerson the Court held that this doctrine carries over by analogy to contraband discovered through the sense of touch during an otherwise lawful search.¹³ If an officer lawfully pats down a suspect's outer clothing and feels an object whose contour or mass makes its identity as contraband immediately apparent, the officer may seize it without a warrant.¹⁴ Each piece of the sight-based test has a tactile counterpart. The lawful vantage point becomes the lawful pat-down, and the visible character of the object becomes the character the hand detects through the cloth. The meaning of immediately apparent stays the same as well: if the officer would need to do something further to the object to learn what it is, the incriminating character was not apparent, and the doctrine cannot support the seizure.¹⁵

The analogy holds because the reasons for plain view survive the change of sense. The first reason concerns privacy. When contraband is left in open view and an officer observes it from a lawful vantage point, no legitimate expectation of privacy has been invaded, so there is no search apart from the intrusion that put the officer there.¹⁶ A pat-down fits that description, because the frisk has already authorized the officer's hand to be on the suspect's outer clothing, and recognizing what the hand has touched intrudes on nothing further. The second reason is practical. Once the officer knows what the object is, a warrant would add only permission to take something whose identity is already settled, and a trip to a magistrate would often be impracticable and would do little to advance the purposes of the Fourth Amendment.¹⁷ Both reasons are present when the discovery is tactile, which is why the Court treated the extension as an obvious one.

The Minnesota Supreme Court had refused the analogy on two grounds: that touch is inherently less immediate and less reliable than sight, and that touch is far more intrusive into the personal privacy at the core of the Fourth Amendment.¹⁸ The Court answered each objection separately. On reliability, Terry v. Ohio itself rests on the premise that an officer can detect weapons by touch, and Terry upheld a seizure made that way, so touch can reveal an object's nature well enough to support a seizure.¹⁹ Even if touch is generally less reliable than sight, that fact only means officers will less often be able to justify seizing contraband they cannot see. The probable-cause requirement does the screening in either case, because an officer who cannot say from the feel what an object is lacks probable cause to believe it is contraband, and the seizure is barred as too speculative whichever sense was used.²⁰ Lower reliability therefore changes how often the doctrine applies without changing what it requires.

The second objection fails for a different reason. Whatever privacy cost touch carries was incurred when the frisk began, since the intrusion the state court feared had already been authorized by the lawful search for weapons.²¹ Taking an item whose identity is already known occasions no additional invasion, so a categorical ban on seizing contraband plainly detected by touch would protect no privacy interest that the frisk had left standing.²² The same instinct appeared a decade earlier in Michigan v. Long, where the Court upheld a protective search of a car's passenger compartment, limited to places where a weapon could be hidden, and added that an officer who finds contraband other than weapons during such a legitimate Terry search cannot be required to ignore it, and the Fourth Amendment does not require its suppression.²³ Dickerson carries that reasoning from the car to the person and keeps the same boundary: what the officer may take is what the lawful search has already revealed, and nothing more.

Touch is one instance of a wider principle. Officers who are lawfully present may use all of their senses, so what an officer smells or hears from a lawful position is analyzed along lines similar to what the officer sees.²⁴ The limit in each case is the scope of the authority that put the officer there. If the officer has the right to touch a person or a bag and the touching alone supplies probable cause, the touching is not a search, but an officer who goes beyond what was authorized, such as one who squeezes a bag that the officer was permitted only to pick up and move, has conducted a search.²⁵ That boundary is the subject of Bond v. United States, and it anticipates the second holding in Dickerson, taken up in the next section.

Because plain feel adds nothing to what the frisk already allows, the first thing to test on any tactile-discovery fact pattern is the frisk itself. Dickerson framed the dispositive question as whether the officer was acting within lawful bounds at the moment the officer gained probable cause to believe the object was contraband.²⁶ One changed fact shows how the answer moves.

The two scenes differ in one variable, the lawfulness of the frisk. The pocket, the package, and the feel are the same in both, and only the first officer's hand was lawfully on the clothing when the package was detected. Answers on this topic usually go wrong by starting with the lump and skipping whether the frisk itself was lawful, a mistake that treats plain feel as a free-standing power to search for drugs. In Dickerson itself, the officer's own testimony about examining the lump with his fingers after the frisk found no weapon shows that a lawful frisk is still not the whole story, and the next section takes up that limit.

Limits of the Frisk

The first holding in Dickerson lets touch do the work of sight, and the second holding marks where touch must stop. A Terry pat-down is a narrow intrusion permitted on less than probable cause, and the narrowness is the price of that lower threshold. Its scope is generally limited to a pat-down of the outer clothing for concealed instruments of assault. The objective purpose of the search draws the line: a search aimed at finding weapons is a frisk and needs only reasonable suspicion that the person is armed and dangerous, while a search aimed at discovering evidence needs probable cause and may need a warrant.²⁸ For a lump in a pocket, that means an officer may handle the lump as far as is necessary to learn whether it is a weapon. Manipulation beyond what is necessary to make that determination exceeds Terry and renders the seizure unlawful.²⁹

The rule rests on two reasons, one functional and one about incentives. The functional reason is that the officer's authority to touch a stranger's clothing rests entirely on danger, so once the officer concludes that the object is not a weapon, the danger has been answered and nothing remains to justify handling it further. The same limit governs protective searches generally: in Michigan v. Long the Court upheld a search of a car's passenger compartment because it was confined to places where a weapon could be hidden, which kept it strictly within the exigency that justified it.³⁰ A dissent in that case, objecting that the majority's rule had no stopping point, framed the issue the same way, since it treated the scope of a search as depending on both its purpose and its intrusiveness.³¹ The incentive reason is subtler. Plain view and plain feel both require that incriminating character be immediately apparent. If an officer could keep squeezing a suspicious lump until it gave up its identity, every lump could be examined until the officer felt sure, and probable cause would be manufactured by the very search it is supposed to precede. Holding the officer to what the weapons question requires removes the temptation to turn a safety frisk into a general search for evidence.

In Minnesota v. Dickerson the order of events decides the result. The pat-down of the front of Dickerson's body revealed no weapons, and the officer then took an interest in a small lump in the nylon jacket.³² By the officer's own testimony, he examined the lump with his fingers, it slid, and it then felt like crack cocaine in cellophane.³³ Put those facts against the rule. The weapons question was answered when the frisk found no weapon, so whatever the officer did next was no longer part of the protective search. The examining and sliding were a further search for evidence, and the officer's belief that the lump was cocaine was a product of that search rather than of the lawful touch that came before it. The seizure was therefore unlawful, and the cocaine could not be used against Dickerson.³⁴

The hinge in this analysis is timing. The question the Court put was whether the officer was acting within the lawful bounds of Terry at the moment he gained probable cause to believe the lump was contraband.³⁵ The record on exactly when that belief formed was not perfectly crisp, and one Justice would have sent the case back for more precise findings on the point, but the Court affirmed on the strength of the officer's own description of what he did with the lump. On an exam, the fact pattern will usually supply the sequence directly, and the answer follows from asking what the officer knew at the moment the weapons question was resolved.

The same principle decided Arizona v. Hicks, where the setting was a lawful entry rather than a frisk. Officers who were inside an apartment for a lawful reason tilted a turntable to read its serial number, and that movement was a separate search. Because the officers had only reasonable suspicion that the equipment was stolen, the search was unlawful, since probable cause had to exist before the object was moved.³⁶ In each case the officer had authority to do one thing, to look in Hicks and to pat for weapons in Dickerson, and that authorized act did not reveal that the object was contraband. The officer then did something more to find out, and the extra act was a search that had to be justified by what the officer already knew, not by what it turned up. The two cases differ in what the extra act was measured against. Hicks asked how much suspicion an officer needs before moving an object in plain view, and the answer was probable cause. Dickerson involved a frisk whose only warrant is the search for weapons, so handling aimed at identifying the lump, after the weapons question was settled, had no authority behind it at all.

The rule leaves room for handling that is necessary to answer the weapons question, so an officer who feels a hard object that might be a gun may keep exploring until the doubt is resolved.³⁷ Answers on this topic go wrong by treating the officer's eventual certainty as the test. The officer in Dickerson was certain by the time he reached into the pocket, but certainty reached through an unauthorized manipulation does not supply probable cause the law will credit. The sound approach looks backward from the seizure to the earliest moment the officer could have identified the object, and asks whether the officer was still inside the frisk at that moment.
