Blogfan Sam writes in from Hawaii:

"Just a theory, but the only reason this is even news is because the David Letterman story made such big news. It's the way the news business works. One big story opens the door for similar stories that wouldn't ordinarily be national news (or even local news). Example, one female teacher is caugth having sex with a student making national news, then suddenly any such story is automaticly national news. No doubt teachers had sex with students before this, but it never made news. Really, who cares if a sportscaster cheats on his wife with a co-worker? The rest of the world doesn't really need to know. Those involved have enough to worry about without being on national news."
