Three words:

World Wide Web

This means this site can be accessed by any one.
Could be Bin Laden is posting about how upset he is with his sister....you just never know.
And, this isn't to spook anyone.
But, if you are going to bare it on a site that can be seen from "Asia to New Zealand and beyond" then you have to believe anyone, at any time can log on and read.

Isn't that right Mr. Bush??
