On a publicly funded school campus, second amendment rights apply. In California in particular, privacy laws apply. I work on a CSU campus as a network analyst. We are not permitted to keep any logs that can link any individual user to any particular destination ip address. We are not permitted to keep outbound firewall logs or any inbound logs that relate to outbound state initiation. We are certainly not permitted to intercept or block encrypted communications in anyway that would otherwise normally be allowed. This applies equally to staff, faculty and students.
