The punchline -

"The government lawyers, despite being asked five times by the judge to guarantee that we plaintiffs would not be charged under the law for our activities, refused to give any assurances. They did not provide assurances because under the law there were none. We could, even they tacitly admitted, be subject to these coercive measures. We too could be swept away into a black hole. And this, I think, decided the case."

Indeed.
