If I take the high-profile “rape” trials I know about as a guide (mere allegations, scant or no evidence, a hungry press and tons of lawyers) this could take a long, long while with much opportunity for Assange to say whatever he wants and a lot of pressure for all involved parties. It’s not as though Sweden can lock him up and throw away the keys. He is relatively safe in British or Swedish custody, if anything were to happen to him the respective governments would get massive problems and there would be no plausible deniability.
"Assange has also said that he declined to return to Sweden to face prosecutors because he feared he would not receive a fair trial, and prosecutors had requested that he be held in solitary confinement and incommunicado."
Not only has there been nothing resembling an "age of democracy" in modern times, but Julian Assange doesn't stand for democracy in any way, shape, or form.
He has indeed demonstrated that modern technology combined with antiquated practice can enable a single person to control our institutions for his own purposes.
Not really sure how that got mistaken with democracy. Let's use our words carefully and precisely. Did you mean the "age of free speech"?
