Tell this to Julian Assange, or to Peter Sunde, Fredrik Neij, Gottfrid Svartholm, and Carl Lundström. Though these are examples of government pressure in the opposite direction, they are still examples of how despite having no legal powers to intervene there is plenty of de-facto power being wielded by the U.S. over the Swedish justice system.
