The government argued in its brief in opposition to the
motion that Megaupload's position "leads to the incredible
conclusion that a foreign corporation can commit crimes in
the United States and secure what amounts to complete
immunity from prosecution simply by ensuring that it has no
principal place of business here."
"Woah, woah, you're trying to tell me that people in other countries DON'T have to obey all our laws?!"
Seems that this may hinge on what "place of business" and "mailed" can be construed to mean with an online business. MegaUpload's primary "place of business" is the internet. So maybe all the government has to do is email MegaUpload a copy?
