I mentioned this elsewhere online, but my take on the matter is that the context provides the critical illumination with which to interpret these comments.
The police that are currently fielded are sectarian and infiltrated. As such, they do not carry the universal public trust and respect that is necessary for a police force to carry out their duty of creating and preserving the public peace.
She's pissed that the non sectarian forces that are not tainted and _could_ gain and retain the public trust are not being fielded.
As a result of this, there is a power vacuum created by the general failure to create the public peace. In this context, the middle eastern version of the Hatfields and McCoys play out their centuries old blood feud.
I think Rice is more interested in establishing a strong, fair and universally respected civil police than in repudiating anything, or disarming anyone.
I would also refer members to many posts that took place during Al-Sadr's brief reign in the graveyard, and the Fallujah insurgency, concerning the abuse of the term "militia" to describe quasi organized para military sectarian/partisan thuggery.
A true militia serves the common defense, the common good, and the cause of justice for all. An armed group that serves anything less is not a true militia, it is a degenerate case.
I'm inclined to believe she chose her words poorly. I see this as more about establishing bona fide justice through a strong and impartial civil mechanism than as a statement of statism.
Why do we respect the Texas Rangers?
They're strong. They're fair. They're not corrupt. They serve the peace, the common good, and the cause of justice for all.
