OPINION
Appellant Timothy Dickerson was charged with possession of a controlled substance in the fifth degree. He challenged the admission of the crack cocaine seized by a police officer. After an eviden-tiary hearing, the trial court held the stop and search of appellant was justified. The trial court also held seizure of the crack was valid based on the plain feel exception to the warrant requirement. We reverse.
FACTS
On November 9, 1989, at approximately 8:15 p.m., Minneapolis police officers Vernon D. Rose and Bruce S. Johnson were *464 patrolling the 1000 block of Morgan Avenue North in a marked patrol ear. Rose is a 14-year police veteran and has participated in approximately 75 drug search warrant executions and 50-75 drug-related arrests. Rose described the 12-unit apartment building at 1030 Morgan Avenue North as a “known crack house.” He previously executed several drug-related search warrants at the address. Drugs, guns, and knives were seized during the searches.
Rose saw appellant Timothy Dickerson leaving the Morgan Avenue apartment building. Rose neither recognized Dickerson nor identified which apartment Dickerson left. According to Rose, Dickerson walked down the stairs and continued toward the sidewalk. Dickerson then made eye contact with Rose, immediately turned around, and began walking toward a side alley. Rose described Dickerson’s movement as “abrupt”.
Rose decided to stop Dickerson based upon his knowledge of past activities at the Morgan Avenue apartments and Dickerson’s abrupt direction change. Rose admitted he did not suspect Dickerson of criminal activity before Dickerson’s direction change.
The officers pulled into the alley and stopped Dickerson. Dickerson made no evasive movements and did not attempt to conceal anything. Rose did not notice any suspicious bulges in Dickerson’s clothing. Dickerson, in contrast, testified he left the building and turned immediately toward the sidewalk leading to an alley. He denied making eye contact with Rose or making an abrupt direction change. Dickerson indicated he did not see the squad car until it drove toward him in the alley.
After stopping Dickerson, Rose performed a pat search. He testified he searched Dickerson because other weapons had been seized from people at the Morgan Avenue apartments. He also indicated that in his experience, drug traffickers often possess weapons.
During the pat search, Rose felt a small lump in the front pocket of Dickerson’s nylon jacket. He examined the lump through the nylon with his fingers. Later he claimed that based upon his experience he knew immediately the lump was crack cocaine tied in cellophane wrap. He seized the crack cocaine and arrested Dickerson. Rose pever thought the lump was a weapon.
The trial court concluded Dickerson’s departure from a “known crack house” and his evasive conduct provided reasonable suspicion he was engaged in criminal activity. The trial court also found the police officer’s pat search was justified based upon prior seizure of weapons in the area and Dickerson’s conduct. Finally, the trial court held the crack seizure valid based upon a “plain feel” exception to the warrant requirement.
ISSUES
1. Was the stop justified?
2. Did the police have an articulable factual basis to believe Dickerson may have been armed and dangerous?
3. May the state justify the seizure under a “plain feel” exception to the warrant requirement?
4. May the state justify the seizure based upon a search incident to arrest theory not presented to the trial court?
ANALYSIS
I.
Whether the stop in this case was valid is purely a legal determination on given facts. Hence we analyze the testimony of the officer and determine whether his observations provided an adequate basis for the stop.
Berge v. Commissioner of Pub. Safety,
Dickerson contends the police performed an unconstitutional investigative stop. The state argues the police properly stopped Dickerson pursuant to
Terry v. Ohio,
The fourth amendment protects the peoples’ right against unreasonable
*465
searches and seizures. U.S. Const, amend. IV. Seizures conducted without a warrant are per se unreasonable unless one of the exceptions to the warrant requirement is applicable.
See United. States v. Place,
One exception to the general warrant rule permits officers to stop and frisk an individual “for purposes of investigating possible criminal behavior even though there is no probable cause to make an arrest.”
Terry,
An investigatory stop and frisk may be performed when law enforcement officers have a reasonable suspicion criminal activity “may be afoot.”
Id.
at 30,
We conclude Dickerson’s stop was justified. First, evasive conduct alone has been held to justify an investigative stop.
Johnson,
II.
An officer may conduct a pat search of a lawfully stopped person if the officer has an objective, articulable basis for thinking the person may be armed and dangerous.
Wold v. State,
We conclude Rose had an articula-ble objective basis to perform a limited pat search. Rose previously seized drugs and weapons from the Morgan Avenue apartments. Rose also testified from experience that drug possessors often carry weapons. Dickerson’s departure from a “known crack house,” his evasive conduct, and Rose’s experience with weapon-carrying drug traffickers provided specific and artic-ulable facts to justify the pat search.
We conclude, however, the scope of the pat search exceeded constitutional parameters. The
Terry
analysis includes the principle that “a search which is reasonable at its inception may violate the Fourth Amendment by virtue of its intolerable intensity and scope.”
Terry,
Terry described the rationale and scope of a pat search:
The sole justification of the search * * * is the protection of the police officer and others nearby, and it must therefore be confined in scope to an intrusion reasonably designed to discover guns, knives, clubs, or other hidden instruments for the assault of the police officer.
*466
Id.
at 29,
confined his search strictly to what was minimally necessary to learn whether the men were armed and to disarm them once he discovered the weapons. He did not conduct a general exploratory search for whatever evidence of criminal activity he might find.
Id.
at 30,
In a companion case to Terry, the Supreme Court reversed a heroin possession conviction and emphasized the limited scope of a pat search. The Court noted:
The search was not reasonably limited in scope to the accomplishment of the only goal which might conceivably have justified its inception — the protection of the officer by disarming a potentially dangerous man. Such a search violates the guaranty of the Fourth Amendment, which protects the sanctity of the person against unreasonable intrusions on the part of all government agents.
Sibron v. New York,
We read Terry and Sibron as limiting pat searches to a careful exploration of the outer surfaces of the person’s clothing until and unless the officer discovers specific and articulable facts reasonably supporting the suspicion that the defendant is armed and dangerous. Absent probable cause to arrest, the officer may exceed the scope of a limited pat search and reach into the suspect’s clothing only for the purpose of recovering an object thought to be a weapon.
The Minnesota Supreme Court has also emphasized the limited scope of a pat search.
In a typical pat-down frisk, only certain “tactile sensations produced by the pat-down will justify a further intrusion into the clothing” to seize the object and the “better view” is that “a search is not permissible when the object felt is soft in nature.”
State v. Alesso,
We hold that the scope of a pat search must be strictly limited to a search for weapons. Absent probable cause for further intrusion, an officer performing a proper Terry frisk may not seize an object unless it reasonably resembles a weapon. Consequently, the trial court erred in concluding Rose’s seizure of the cocaine was constitutional.
III.
The trial court concluded the plain feel exception to the traditional warrant requirement justified the seizure of the cocaine. We disagree, and in so doing, decline to adopt the plain feel exception in Minnesota.
Courts that have addressed the “plain feel” issue have treated it as a corollary to
*467
the plain view doctrine.
See United States v. Williams,
Courts invoke the plain view exception when an officer engaged in a lawful search views an object which he or she had probable cause to believe was contraband. The plain view exception is justified because apprehension of an object already in plain view of an officer lawfully present does not infringe any reasonable expectation of privacy, and “its exposure thus is not a search within the meaning of the Fourth Amendment.”
United States v. Williams,
We decline to adopt a plain feel exception to the warrant requirement. We believe the proper analysis in this ease must focus upon the limited purpose associated with a pat search. We conclude the search of Dickerson exceeded constitutional parameters and we therefore reverse.
IV.
The state argues for the first time on appeal that the search was justified as incident to an arrest. A search is valid as incident to arrest even if conducted before the actual arrest provided (1) the arrest and the search are substantially contemporaneous; and (2) probable cause to arrest existed before the search.
Rawlings v. Kentucky,
The state, however, did not argue this theory to the trial court. The record indicates the state argued only a “plain feel” analysis. At oral argument, the state admitted it failed to present the search incident to arrest theory to the trial court. Parties cannot raise for the first time on appeal issues not presented to the trial court.
State v. Sorenson,
DECISION
The trial court did not err by concluding the police officers properly stopped appellant. However, the pat search of appellant by the police officer exceeded constitutional parameters. We decline to adopt the plain feel exception to the warrant requirement.
Reversed.
