If you've been to the CIS offices in Portland, and on the entire 5th floor of a block sized building you realize that yes, you cannot see the employees for the stacks of files that there are no cabinets for, and no place to put even people that have already been "deported" except a facility in Tacoma that overflowed its capacity in about 1993...  it gives a dfferent emphasis to these comments. Cynically, people rely on a swamped system to be unable to enforce anything, even criminals.  As to the Muslim issues, perhaps take a look at the work of "muslims" who are progressive and compare it with Trump's views.  See Azra Nomani http://www.asranomani.com/ or Raheel Raza's work  go.clarionproject.org/numbers-full-film/   it's an interesting question if the culture of the west and the doctrines of Islam are mortally/mutually exclusive. It may be the cause of civil liberties and freedom of religion are caught in the middle of a desperate hope we can avoid acknowledging there's a real problem.
