"There were a lot of people on stage," he said. "There's a lot of questions as to what happened with this young man—that's all still to come out in trial."

Asked if he thought the U.S. government should have intervened on his behalf, Blythe called it a "sticky question."

"The Czech legal system is different, and from what I understand, I was given due process," he said. "I was not imprisoned in America. That was the first thing that I had to realize and keep in mind—'We're playing by different rules here.' I certainly would have appreciated a little bit more concern on my part."

According to Czech news site Novinky.cz, prosecutors in Prague now have three months to set a trial date or request further investigation.
