She's asked this question before while pointing to the picture with the pant leg, stockinged foot, and Travis with blood running down his right shoulder, and his foot closest to the bathroom end of the hallway. You all know that photo. The 'dragging' photo. She wants people to believe that Travis was holding his head and arm up, instead of him being physically moved by JA, or his head resting on some part of her body while she holds his arm up.
ETA: and that the blood is from the gunshot wound to his head, instead of his slashed throat. → gunshot first theory of the defense.
