You're killing me with these funky legal analyses. I doubt you've ever set foot in a US courtroom.
Actually, last time I checked "US Courts" just applies over "US Citizens", and by the IP mtgox is displaying I get this:
201.191.115.114 CR Costa Rica 03 Guanacaste Liberia 10.6333 -85.4333 Instituto Costarricense de Electricidad y Telecom. Instituto Costarricense de Electricidad y Telecom.
resolves to 74.52.143.58 which appears to be an ISP in Houston TX...
