In all seriousness, if this is your U.S. passport I cannot believe the passport bureau would be uninterested because they should have a procedure for canceling out or flagging a passport that is reported lost or stolen. Also, some law enforcement agency could easily show up if someone uses that passport for an illegal activity. So I'd start with the passport bureau and ask their procedures, file a police report, maybe contact the closest FBI office and ask for advice. Does the State Dept. handle passports? But obviously the passport is gone, no one is going to find it unless it is being used somewhere by the crook.
Of course I am concerned for my own situation.
But more than that, I am amazed how relaxed everyone
at the Passport agency is.
After all the problems we have had with security these
last few years, I would think that would have a higher
sense of urgency.....
