"The Feds Have Figured Out How To Hack The Secret Internet For Criminals"

I thought "Tor", "Darknet" and "Deep Web" referred to three different things. "Tor" for example, is a way to anonymously use The Internet, as well as to serve things anonymously and without giving away the server's location. I thought a "darknet" was just a non-public network, maybe something that you get invited to use, and maybe have to use special URLs to get to. You didn't necessarily need to use Tor to get to a given darkent.

Anyway, the whole article seems overheated, in a William-Gibsonesque way.
