Also known as: plain-touch · plain touch doctrine · plain feel
Written by attorneys · grounded in primary & secondary sources — see below
A doctrine permitting an officer conducting a lawful Terry patdown to seize an object whose incriminating character as contraband or a weapon is immediately apparent from its feel. Manipulation of the object beyond what is necessary to determine whether it is a weapon exceeds the scope of a Terry frisk and renders the seizure unlawful.
Officer Chen stopped Luis on reasonable suspicion that he was armed and conducted a lawful Terry patdown of his outer clothing. Chen felt a small plastic-wrapped tube strapped to Luis's ankle and slid his fingers along its length before pulling it off. The tube contained powdered drugs. Because the additional sliding went beyond determining whether the object was a weapon, the seizure violated the Fourth Amendment.
During a lawful patdown of Pedro Pacheco after a bar fight, Officer Lopez felt a hard rectangular object in Pacheco's pocket that immediately felt like a knife handle. Lopez seized the object without further manipulation and discovered it was a switchblade. The immediate apparentness of the weapon from the initial touch justified the seizure under the plain touch doctrine.

The officer must be conducting a lawful Terry patdown for weapons. The object's incriminating character as contraband or a weapon must be immediately apparent from the initial lawful touch. Any further manipulation to investigate the object exceeds the frisk's scope.
Supporting sources
No. Squeezing or kneading exceeds the limited purpose of a Terry frisk, which is only to determine whether the suspect is armed. The doctrine requires that the contraband nature be immediately apparent without additional probing.
Supporting sources
The seizure becomes unlawful under the Fourth Amendment. Evidence obtained through that manipulation must be suppressed as the fruit of an unconstitutional search.
