Text Messaging

So I just got back from Tech PETE and I decided that I needed to blog about this article I just read. It said that a mayor in Michigan got caught having an affair with one of his staff after his text messages were revealed to be scandelous and he lied under oath about it. Now I don't know about you, but I don't like that people can find that much information about what is being said and sent. That stuff is sometimes private, and between you and the reciever. How in the world did technology get to the point where you can read every text message sent through this cell phone network? The fact that the cell phone company has the details to that much information amazes me. I am kind of indifferent on this subject because I think that the fact that it can reveal so much might help out in murder cases, scandals, etc and that would be great to catch the people who do that kind of thing. However, I do think it's an invasion of privacy and I don't want some random cell phone operator reading my texts. Anyone have any opinions on the subject?
