Wherever Snowden goes next, U.S. officials have said they plan to push to prosecute him. But Jonathan Turley, a law professor at George Washington University, told CNN that extradition treaties "are read differently by countries in different circumstances."
The United States has its share of critics who say it ignores international law regarding the treatment of prisoners or the use of drone attacks, and host countries are allowed to question "whether a charged crime was a political act."
"It doesn't help to have all these senators and members of Congress calling for this guy's head," Turley said, referring to lawmakers who have accused Snowden of treason. "All this hue and cry adds to the sort of political perspective of this case. That is not going to help the U.S. State Department or the Justice Department."
