From Pacific Justice:

Students attending an educational conference in the California Capitol building were accosted by security for singing the "Star Spangled Banner" and "God Bless America." The students were participating in City on the Hill, which teaches students the fundamentals of the legislative process. Approximately forty-five students were in the rotunda and, inspired by the grandeur of the setting and their feelings of patriotism, began to spontaneously sing. A sergeant at arms and four Highway Patrol Officers asserted to the City on the Hill staff that the students required a permit to sing.
