Speaking of Spencer, his Nation article based on his reporting in Iraq is finally out and about. " Training Iraq's Death Squads," is a good title and gives a general sense of things. Also this:
The militias hardly command the loyalty of every policeman. But police commanders warn that sectarianism has seeped thoroughly into the security apparatus, and it threatens to undermine everything McNellis and his colleagues have accomplished. The professional police they desire may instead become a sharper instrument of sectarian fury.
Right. Politics always comes first. Really well-trained security services do not a pluralistic democracy make.
