A Proper "Frisk" Under the Stop-And-Frisk Rules Established by Terry

A proper "frisk" under the stop-and-frisk rules established by Terry v. Ohio:

A) is limited to a pat-down of the suspect's outer clothing unless something that could be a weapon is felt during the pat-down.
B) may not be conducted unless there is no doubt in the mind of the officer that the suspect has a weapon.
C) may include a search of an area within one hundred yards of the suspect if the pat-down results in the feeling of an object which could be a weapon.
D) may not even extend to a pat-down unless the officer has probable cause to believe the suspect has a weapon.
