Open Window

The open window in Dorothy Vallen's apartment struck me every time I saw it.  I thought about what it could mean for awhile and I decided that it is symbolic of Jeffrey's way out.  At any time, he could walk away and forget about Dorothy.  He didn't have to get involved and he certainly didn't have to stay involved.  When he first went into Dorothy's apartment, he said he was going to find a window to crack open so that he could sneak back in and out without being noticed.  The open window throughout the movie in her apartment symbolizes this same escape.  He could walk away and be completely free from all the trouble, but he stays.
