If there's an actual law and due process, ok. If people are just supposed to automatically comply because somebody in a government agency says so...well, I hope we haven't sunk that far.
I can't wait till they cross the line, and block some .com, then a group in that (non-US) country gets local injunctions forcing it to resolve. It could split DNS or wrestle it out of US control.

The domain has still not been returned.
Having your domain hosted with a reasonable registrar would have been enough to prevent this.
And if it were a true emergency the Government would go straight to Verisign (for .com/net) and not even bother with the registrar.
Although to be fair, the SS just made a request, and GoDaddy had no responsibility to comply, they did so on their own accord without any type of process.
In my book, it's GoDaddy's responsibility to do the right thing, not the SS' responsibility to not complain. If they would have been with a reasonable registrar, this would not have happened.
