If not from that think there is a theory that Sheila ha possibly moved things after washing up.
Or JB had moved them before climbing out of the window.
Yeah I guess so, I'm sure people will pick the one that coincides with their belief of a guilty or innocent JB.
For example, I think he moved items in front of the window to make it appear that nobody has climbed out of the window.

(Actually I don't really have a view on it)
