Firstly, it should be observed that Sergeant Pasquali stated that he had never studied stone throwing apart from this case; he also supported the possibility of "making a parallel with investigations of ballistics and firearms"; the same consultant did, however, admit that, whereas ballistics is a science of precise data [dati certi] (p. 39, hearing of July 3, 2009), "here we have an infinity of possible variations" [abbiamo delle variabili che sono infinite](p. 40). Precisely in relation to these variations and to what has been observed above, the assertion and the explanation he offers for the stone having been thrown from outside cannot be shared by the Court. Indeed, if one supposes that the stone was thrown from the inside with the 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.
