Well in this instance I'm suggesting that the uprooting and deprivation of freedom using foreign law as a basis is unreasonable. I fully admit this is a lay person interpretation and the law likely disagrees, but I would imagine that a more fair process would first let an international court or the local governing body determine in full if they cooperate, not instead have a blanket extradition treaty. Unless I am misunderstanding the entirety of extradition treaties, it just seems the burden of proof that they have the right person to even start questioning is low and not subject to scrutiny except from within.
