Computer Crimes Across Borders

Today, at the request of Dutch authorities, Armenian police arrested the suspected creator of the Bredolab botnet. The botnet consists of over 200,000 infected computers located around the world. Since the hacker is Armenian, should he be tried in an Armenian court, or extradited to Holland or some other country with affected computer owners? I don't think there's a clear answer to that question, and I think that's a big problem. The World Wide Web has eliminated all borders in the digital world, antiquating our current legal systems with boundaries and jurisdictions. Until we establish a world-wide network law, and an agency with authority to enforce it, uncooperative legal systems will continue to hinder finding and prosecuting internet criminals.
