 CONT: When Anderton confronts and then shoots Leo Crow, Agatha is  crawling off the bed and takes most of the pictures off the bed onto  the floor with her. Later, when Witwer and the PreCrime team are  studying the crime scene, the pictures are back on the bed. It is  unlikely that either Anderton or Agatha would have stopped to put  the pictures back on the bed before leaving, and no policeman worth  his salt would have disturbed a crime scene and scooped up the  pictures and put them on the bed.
