Silly me, I always was under the apparently mistaken assumption that in this country, congress passes laws declaring what is legal and illegal and establishing penalties for violation, the executive branch enforces those laws, and the courts adjudicate disputes about those enforcement actions. If Obama can simply completely sidestep the other two branches of government with a stroke of a pen, we might as well lay off all the worthies in the legislative and judicial branch and declare The One dictator for life.
What amazes me is that DHS openly says that deportation itself is the threat, not the illegals being deported. It just shows whose side they are on (i.e. not ours).
