I'm of the mindset that I want my castle to be as hardened as possible. Spineless thieves will usually take the path of least resistance to minimize the time pilfering and reduce the likelihood of getting caught.
A good op and I like this idea here. I get the idea of making it look already ransacked, but in a long term bug in I want as much deterrent as possible. It will slow down targets, provide early warning (some type of movement/noise set up i.e. tin cans and rocks). Plus I think your average ****bags will follow the path of least resistance.
