They still seem to think that they will show up!

Fugitive Operations: Currently, there are more than 450,000 absconders, and that number is growing at a rate of 40,000 per year. DHS will expand the national fugitive operations program so that in 10 years, DHS will eliminate the fugitive absconder population assuming appropriate resources. To achieve this goal will require the establishment of 100 fugitive operations teams nationwide (up from the current 44) as well as increased efficiencies in the program.
