Kevin, you've misunderstood Massei's reconstruction of the window breaking. You may wish to look at the photos on PMF or Bruce's site to aid in understanding the reconstruction. I quote from the MOTIVATIONS report, English Translation, page 52:
"Indeed, if one supposes that the stone was thrown from the inside with the [exterior] shutters pulled closed (as they must have been according to statements cited above), but with the casement holding the pane somewhat open, with the inner shutter behind it, then here is a situation analogous to that of throwing the stone from the outside (the rock would hit the window in the same place as if it came from the outside), and under the shock of the large stone, because of the resistance of the inner shutter behind the window-pane (the shield effect as one might say), the pieces of glass would necessarily fall down on the windowsill both inside and outside (considering the casement as having being only slightly open, and thus the smashed pane positioned near to the windowsill). The presence of the shutters pulled inwards, as described by Romanelli, would have prevented the pieces of glass from falling to the ground below, as indeed they did not, but as they surely would have had the stone been thrown from the outside. As for the presence of glass in Romanelli's room, the violence of the blow, the characteristics of the glass (which was rather thin as indicated by Romanelli and Pasquali), the large rock used, and finally the shield effect caused by the inner shutter hanging half-open behind the glass pane [41] (a position of the inner shutter which corresponds to the scratch on it visible in the photos) give an adequate explanation of the distribution of the glass."
Whoever simulated this, threw the rock from inside of Filomena's room. The two exterior shutters were closed, or nearly closed. Likewise the two interior shutters--or "shades"-- behind the two glass window panes were closed, or nearly so. But the two casements---the frames holding the panes of glass--- were open. The one on the right---as seen from within the room--- was probably completely swung open. The casement on the left, maybe just swung half open. Then the rock was thrown through the glass in the left casement, the rock striking the exterior surface of the glass pane, and then striking the exterior surface of the respective "shade," leaving a scar (as seen).Therefore the rock is headed into Filomena's room, not exiting toward the louvered exterior shutters.
