The Defense III

The plot thickens:

Graner told Pohl that pictures he took of England holding the leash were meant to be used as a training aid for other guards. But England had told Pohl when she entered her plea that the pictures were being taken purely for the amusement of the guards. (emphasis added)

Excuse me, but it they were meant to be used as a "training aid" then sombody was doing the training. This would, one would hope, not be oxygen deprived and educationally challanged Lynndie England. Does the term fall girl mean anything here?
