I think that there should be because one should not be forced to testify about confidential information which could be construed as a violation of the constitution and because the government should not force people to talk about something that they do not want to especially if they are trying to protect someone from danger.
Not sure what it means, but it sounds like if you are a reporter you get a privlege over those who are not in something. Maybe the right to cut lines, or get ahead of everyone else. Get behind scenes and such. I think they should have to wait like everyone else.
