Being accused of vandalism in school?

[Renard]

Okay so one night, someone sneaked into the school compound and vandalized all the locks. Someone put glue in "all" the keyholes and tomorrow, the principals are going to have a meeting with me and my parents. At first, they said they caught me on Camera in which i repeatedly demanded them to show me the "evidence" but they won't show me until tomorrow. Also, the principals said that other people went up and told the administrators that it was me the vandalized the school. Do I have the right to confront or at least know who accused me of something that I didn't do? Because the principals won't tell me who accused me of the vandalism.
With what evidence? I wasn't there so get out. @Marcus
