"Rape by instrumentality"

From a Harper's piece on a Guantanamo prison guard talking,

I participated in some Capitol Hill negotiations with White House representatives relating to legislation creating criminal law accountability for contractors. The Bush White House vehemently objected to provisions of the law dealing with rape by instrumentality. When House negotiators pressed to know why, they were met first with silence and then an embarrassed acknowledgement that a key part of the Bush program included invasion of the bodies of prisoners in a way that might be deemed rape by instrumentality under existing federal and state criminal statutes.
