I understand why you felt violated and I'm sorry that happened to you. I think it's odd you seem to attribute none of the violation to campus security. You describe them as passively compelled to follow up on a complaint about a student's (I'm presuming reasonable) on-campus behaviour by going into the student newspaper office they worked in and reading their work. But they chose to do that. They could have handled things differently, such as talk to you versus snoop like they did or dismiss you as a non-threat
