It's my understanding that it will be a roundtable discussion and that there will be a Q&A session. BUT, there will be no one-on-one interviews afterward.
Presumably, the Q&A session will only be about the scientific matters discussed in the presentations. They won't answer questions about investigative or prosecutorial aspects of the case.
What bothers me is that, if there are a hundred reporters present, we're likely to get a hundred different points of view of what was said.
