Here is a link to a book review about crimes that take place on line and across national boundaries. The internet affords challenges to national boundaries. We see that in the Wikileaks & Julian Assange situation. We see that with online gambling, such as online poker. The Pentagon is promoting the idea of cyberwarfare that will take place across national boundaries. In fact, the US flies drones over Pakistan from workstations located at airbases in the US. EBay and Yahoo and Google have all encountered that in the Middle East and China, which have different ideas from those in the US about what it is appropriate for individual citizens to see.
It isn't surprising that crimes take place across national boundaries, too. Here are the two books from the review:
