No, you're just creating problems to make it sound implausible. It would not be surprising to find an intruder remembered to bring a flashlight; it would not be surprising that someone could find the bathroom without turning on the laundry light; also, if the bathroom door opens the way it shows in the police generated floor plan, he wouldn't even have to leave his seat to turn off the bathroom light and close the door, wouldn't even have to close the door all the way.
Thanks for bringing back the common sense.
