Here's another example of the INS / ICE being the worst-run agency in DC, with the possible exception of the Bureau of Indian Affairs.
Anything in the DHS is a black hole (FEMA is in there too). IT was a mistake to create DHS, and Bush (who didn't like the idea) hasn't done a good job in getting anything to work in DHS.
What do you expect from any agency within the bureaucratic nightmare that is the Department of Homeland Insecurity?
