The purpose of the Wood/Dr. Phil set up was to create an innocent reason for Burke to have handled the flashlight, not John. CBS didn't conclude John used the flashlight to bash JBR in the head. But in advance of the CBS broadcast, Lin/Phil apparently felt they needed a simple explanation for a flashlight to be within Burke's easy reach for his late wanderings, otherwise he would have had to seek and find it on his own, and such an admission might not look too good. What to do? Let's create a brand new story about John leading Burke to bed with a flashlight and imply that perhaps Burke simply grabbed it off his bedside table to sneak downstairs after everyone else was in bed. He can't remember for sure, of course, but he very well might have used it. Innocent Reason For Burke To Have Handled Flashlight - Check.
