> It is really a difficult call.
In my view it isn't, USA has chosen common law jurisdiction which clearly states "Innocent until proven guilty". So it should not just put it on the books, but has to follow it in spirit. Don't create border buffer zones, guam to dilute it, this is taking USA to same level as other nations which it criticize for those violations.
In Continental law in few jurisdiction like Japan (what happened with Carlos Ghosn) and China they follow "Guilty until proven innocent". In this jurisdiction the prosecutor exercise control on whom to prosecute, because onus is on plaintiff to prove innocence through evidence.
Here the discussion is not about what is happening inside the country, but at the borders so surveillance state is not a question here.
If you have discussion on surveillance, China is a transparent surveillance where citizens are aware of it, USA with NSA is an opaque surveillance state. I am sure I don't want either of them, but if forced prefer a transparent than an opaque system.
