which case created the plain feel doctrine
Plain Feel Doctrine The plain feel doctrine allows a police officer to seize the objects during an otherwise legitimate pat-down search if by plain feel he reasonably believes to be contraband. The plain view doctrine applies by analogy to cases where a police officer discovers contraband by plain feel or touch during an otherwise lawful search. Objects observed in plain view or by detected by plain touch during a lawful search can be admissible evidence if its incriminating character is immediately identifiable.
