Respond to the following quote below:

"In 2010, the Director of Immigration and Customs Enforcement finally put in writing what every Border Patrol Agent, Deportation Officer, and Special Agent had known for year: there's just too many of them. The current infrastructure of the Department of Homeland Security can remove (deport) about 400,000 aliens per year. It is estimated that there are about 16,000,000 aliens present in the United States in violation of immigration law. The position of ICE is that they will continue to use the 400,000 capacity to remove terrorists and criminals. What alternative do you suggest? How can DHS deal with 16,000,000 illegal aliens? Or should they?"
