Facebook TMI

Should the media be able to tap into Facebook for information? Ever since the governor of New York was caught in that hooker scandal, the media has been running photos of girl in question. Now, in East Lansing, MSU police have been tapping into the online networking site for photos and information about the attendees. Is prying into these sites an invasion of privacy? When I signed up, I never agreed to have my information released to media if I was involved in an altercation. I guess this is the new frontier of investigative journalism, I thought it was just a place to meet people.
