contesting extradition isn't with the aim of actually succeeding, but more so to give your defense time to get acquainted with your case and how much the prosecution has as evidence.   a gun, manifesto, smudged hand print from the hotel he stayed, but nothing so far directly connecting him to the murder. so far they have a probable motive and approximate location to the crime scene but that's all it is unless they have more they're not telling.
