It wasn't clear whether the classification means only that U.S. servicemembers are subject to punishment for contact with Wikileaks, or whether the general public is as well. It's one thing to tell employees who are entrusted with state secrets that they should not divulge them to someone who's going to plaster them on the NYTimes; it's another to tell members of the general public that they can't talk to or express support for Wikileaks for fear of criminal sanctions. The latter seems a gross violation of freedom of assembly.
