DHS Secretary Napolitano's letter to congressional Democrats does not confirm whether the administratively-amnestied illegal aliens will receive worker authorization. Nor does it attempt to justify the administration's apparent usurpation of congressional authority.
It does claim that the administrative change will "enhance public safety" by directing ICE to wait until an illegal alien commits a violent crime before considering deportation. Both public safety and logical reasoning have taken a backseat to election politics, it seems.
In the name of efficiency, DHS and the Department of Justice have initiated an "interagency working group to execute a case-by-case review of all individuals currently in removal proceedings." Only in Washington does adding a bureaucratic process create efficiency.
