I am not at all convinced we have the full story here. The Washington Post ran photo's of the front and back of both homes. There is NO WAY you could mistake the two.

One home has a protruding screened porch, a deck and a stairway to the basement. The other has NONE of those. You could NOT be drunk or stoned enough to mistake the backs of those two houses. We may never find out if it was intended burglary, but I believe there was more to it than a simple mistake.
