HeKS said:do we have much reason to think any significant number of people would know about him being under suspicion in the first place - as distinct from all the other people under suspicion at the time - so that a newspaper announcement about him being cleared would be warranted or make sense?
Well, judging by the scene when the Dean gets Indy out of his class, I'd say that once his students got wind of it, the news spread all across the university, and then beyond that as well...
Or we'll just have it be in the school's paper ;)
