got message from this number indicating i was in violation of some federal treasury issue...  which i know to be complete bunk... so i called the number back and left a voicemail at 1am...  "hi.. um, i don't want to go to jail... please don't arrest me... I'll be a good boy.."  then hung up - giving no identifying information... because if they can mess with me, i feel perfectly within my rights to mess with them.
