Query: What state's law requires that capital punishment occur "within the walls" of a penitentiary?
Context: Similarly, a dormant Massachusetts law, see Mass. Gen. Law ch. 279 § 60, required executions to take place "within an enclosure or building." North Carolina General Statute § 15-188 requires death sentences to be executed "within the walls" of the penitentiary, as do Oklahoma Statute Title 22 § 1015 and Montana Code § 46-19-103. Ohio Revised Code § 2949.22 requires that "[t]he enclosure shall exclude public view."
