This is the Embassy's statement:
The U.S. Embassy cannot effect the release of U.S. citizens imprisoned in foreign jails. However, a U.S. consular officer will insist on prompt access to an arrested U.S. citizen, provide a list of attorneys, provide information on the host country's legal system, offer to contact the arrested citizen’s family or friends, visit on a regular basis, protest mistreatment, monitor jail conditions, and keep the Department of State informed.
