Capture, Detain and COIN: merged thread

[PhilR]

Looking for any and all information that may relate to detention operations in COIN. I've gone through FM 3-24 and Galula's Counterinsurgency Warfare. I am also aware of the recent article in Joint Force Quarterly.
What I am looking for goes beyond the TTPs of detainee treatment, how to interrogate, etc. I'm looking for anything that describes how detainee policies were used for IO effect (selective and general release programs, differing cultural perspectives on insurgents being detained vice being killed, etc.).
To my mind its the recognition that a counterinsurgent's COIN battlespace extends "behind the wire;" Its not just from the intelligence that may be gathered, but from the actual fact of detainees being held from a community and how their status may be used in the overall COIN battle. I think it must go beyond the law enforcement impetus to get bad guys off of the street (espeically if the community does not necessarily recognize them as "bad" guys).
Thanks.
