The reason why I think it's the staff is bc if the accuser has a solid proof aka the document, they would just revealed it out right from the start.
I don't think Garams side benefited from the leak so they are also out of questions.
That leaves either the third party which school staff member, or forgery assuming the document does not exist.
What I'm still curious about is leaking only the header of the document and not the full text
Like... if the full text details real bullying by Garam, that would be it, game over.
But in only releasing the header it gives me three scenarios
1. A threat. "We have this, so own up now before we do"
2. The rest of the document actually exonerates Garam. "We did an investigation into Garam and found no wrongdoing from her". The leaker is hiding that because obviously it doesn't match a narrative.
3. It is fake. It's easier to fake a few lines of the document than a whole report
