What does all this have to do with EU membership? When you go to a country you have to respect the laws they have there, as silly as they might be.
That said, in this situation we shouldn't take the initiative and just straight out oppose their membership. Patience is a virtue. Wait and see what they do. If they actually take the initiative to address their own problems, then that can only be a promising sign and one that needs to be encouraged, not at all punished. Yet if they insist on extradition, arrogantly ignoring the problems addressed in the documentary, they will simply jeopardise their own application for membership. We are hardly the only European member state sitting on the fence with regards to their membership.
