I can't believe how unbelievably little people like you know about law and free speech. Are you the one seriously arguing that it's illegal to lie on Twitter? Or to lie a newspaper? Of course faking a document is perfectly legal as long as it's not used for fraud. Tricking people on Twitter or at a newspaper isn't fraud unless they're contractually paying you for authentic documents and you deceive them for monetary gain.

Is this really that hard? The Onion fakes documents all the time and claims to have quotes from police officers and government officials on a daily basis.

Free speech is the most essential of all freedoms, and you'd trade it away for a song and a dance out of sheer ignorance.
