Why didn't he try to escape?

Where in the world would he go? Until he screwed over his host, he was safe there.

He had nowhere else to go. Let's think about it for a second; he was holed up in a small countries embassy(equador?)at the end of a dead end street in London. Nobody wants him now so I imagine he's just better off in the hands of the British authorities for another 5-10 years before he croaks from some stress related disorder.

Give me a break ... there are people in the embassy 7x24 and he did not have access to the whole embassy. Being locked up there for 7 years was worse than being in prison in serious ways. The time he spent was not counting towards any sentence, but I guess he thought he was faced with the death penalty ... which is what a lot of American politicians who were grandstanding called for. I don't think Assange did anything that was that bad, and he did his best not to release government documents that would out any spies. Now we have a glimmer about how dishonest and evil our government can be at times because of him.

the question and your ideas are pretty laughable. flying a helicopter into the middle of london? haha, come on now! same witha tunnel. he was stuck and we went pretty crazy. He should have just given up willingly, but some are out for his life, so he was rightfully scared.
