berkeley high has an open campus, meaning that students can come and go as they please. in theory, outsiders aren't supposed to be able to, but during my tenure there the campus wasn't physically laid out to accommodate access control, so the administration had no real way to keep random people out. the adults, concerned about student safety, experimented with various ways to partially close the campus. none of them worked, because they all required the consent of the governed, and we never gave it.
