Reporters: Liable.
P2P software makers: Liable.
Cable ISPs: Liable.
In ruling that Cable ISPs are not granted "common carrier" protections, it seems to this legal novice that Cable ISPs may be held liable for the content of the communications of their customers.
The P2P case is similar in that software with perfectly legitimate uses may subject its creators to liability if they choose to promote its use in what I consider to be a legally arbitrary way. One man's "promoting piracy" is another man's anonymity.
As a reporter, I'm disturbed by the Miller/Cooper case in that it goes to what a reporter may know even if the reporter doesn't report on that knowledge. Again, squelching the sources.
No doubt I'm a paranoid kook, but it sure looks as if the free flow of factual information just took a big hit from the SCOTUS.
