Re: BK passing DM on his way out of the house, I previously believed that he may have seen her but didn't care because he was disguised (wearing a mask) and had completed his intended mission. The possibility that BK has visual snow has thrown this into question for me. If BK still has visual snow--and from what I've read, it sounds like a chronic condition--this could change everything. It has changed my own ideas about the events of Nov. 13, and I think it likely will influence BK's legal defense strategy.
Here's a brief overview from the Cleveland Clinic:
With visual snow syndrome, you see static whether your eyes are open or shut. Learn more about what it's like looking through a shaken snow globe.

Symptoms include seeing "snow" or "static" everywhere you look, having difficulty seeing in the dark, and insomnia (among other, very unpleasant-sounding symptoms). So I now think it's more probable that BK truly didn't see DM as he was leaving the house. Visual snow also could have made it more difficult for BK to locate the knife sheath, if he did intend to retrieve it. Finally, it seems like some of BK's odd habits, like vacuuming at 1am and being generally very active in the late night and early morning hours, may also be tied to Visual Snow Syndrome.
I was anticipating a novel legal defense in this case, but I'm now getting a sense of just how novel it may wind up being.
