One of the issues with the Internet and email specifically is that when you have an electronic record of things, it becomes much easier to get access to that information and use it against someone.
This is the case recently in Philadelphia, where a male news anchor got access to his female co-anchor's email accounts and leaked negative information about her to the press.
Why does this remind me of the movie Anchorman all of a sudden?
So, in this case, there was proof enough to charge the male anchor with "intentionally accessing a protected computer without authorization" - and he's lost his job as well.
The interesting part is that the female co-anchor was fired in December because she had a run-in or two with the law.
Suddenly I feel like our local news anchors are boring.
