Last month the Washington Post published this piece [1] on how DHS is collecting information on travelers:

"...new details about the information being retained suggest that the government is monitoring the personal habits of travelers more closely than it has previously acknowledged. The details were learned when a group of activists requested copies of official records on their own travel."  

Now you too can find out what DHS knows about you.  The Identity Project [2] has created this site [3] to walk you through the steps to obtain the unclassified portions of your DHS travel dossier.   Bon voyage!
