I looked at the window, the size the height the shutter. The noise to lift the shutters up, then negotiate to slide the window, and then climb in the window which only had a small opening really, would have left scuff marks etc on the wall and sill. I believe there was non?
Also the window was in full view of the car park. Would a burglar choose such an entry? The door i can understand. IF they had the tools they could probably get in the front door easier it was away from the light and set to an angle so no one would have really noticed. It would probably have been less effort to get in the front door.
I had an intruder many years ago with a window similar and a shutter which was slightly raised to give air, and I heard the person immediately as the shutter rattled and so did my sister who was in the room with me and we scared him off. It scared us to death to be honest, and a new security lock was fitted internally, but the shutters do make a noise without doubt.
Noise travels at night surely if someone tampered with the shutter and window the amount of Tapas 7 floating about and OTHER PEOPLE, i.e. residents and holiday makers wouldnt someone have heard it....
Nah for me it never happened. If it dont make sense then it usually isnt. BUT if you wanted to set a scene then opening the window and shutter would be part of the scene that was set by the players.
