Here's the plan. We form a large enough mob of people who are dressed to look exactly like Assange (wigs and all), then he can just run into the mob and disperse, make contact with sympathizers, and flee to a less oppressive country.
Personally I think that by now he should get it over with and walk out, be arrested, do the time for skipping bail and then he can put his extradition theory to the test. The current political leadership in the USA is about as pro Assange as it is ever going to get.
His opponents -- ie: the entire western MSM apparatus -- have been working harder at that, and certainly done much more damage to Wikileaks than Assange could ever manage. Though I don't see how he's damaged the image of Wikileaks or himself much in the last couple of years. With Wikileaks' good works around the 2016 US elections you'd think would have won them plenty of goodwiil -- exposing the sham that is the US electoral system directly from the mouths of its brightest and most powerful.
That's where the immense, ongoing smear via Western MSM outlets comes in though, I suppose.
> walk out, be arrested, do the time
Definitely, just do it. It's easy for us to say, but imagine how terrifying that must be for him: who knows whose dungeon he'll end up in, but that he'll be effectively neutralized in his efficacy in regards to Wikileaks permanently is almost certain -- at the very least!
They are also a much better shot than crime movies would lead you to believe.
