A person commits first-degree trespass when he or she “without authorization . . . enters or remains . . . in a building of another.” G.S. 14-159.12(a). But aren’t members of the public “authoriz[ed]” to enter public buildings? And given that public buildings belong to all of us, do they even count as buildings “of another”? In other words, is it possible to commit a trespass in a public building?
