Two major unions of law enforcement personel who handle immigration, numbering roughly 20,000 people, have united against the proposed immigration reform. The New York Times reports on the announcement:
The labor alliance also raises the influence of the federal officer who leads the union that represents most deportation agents, the National Immigration and Customs Enforcement Council. The officer, Chris Crane, has emerged as a star witness for the opposition to the overhaul and a troublesome adversary for Obama administration officials working to promote it.
I get the concerns, but to be frank, it's a little rich to see a public sector union cheered by conservatives for seeking to protect its own status quo.
