Hawaii has a functioning democracy. If you get arrested, you're entitled to a trial by your peers. You can vote for the President, two Senators, and two Representatives. They have no extradition treaty with China and aren't planning to enact one.

It's a little different than the situation in Hong Kong right now. If the people of Hong Kong voted for Xi Jinping, that would be similar to where Hawaii is.

TL;DR: Hawaii doesn't need to be freed. They are free.
