A jeweler reported a heist. The front window was smashed inward, and diamonds were missing from the velvet tray. The security footage showed a masked figure throwing a heavy cobblestone through the glass at midnight. However, the lead detective noticed all the broken glass shards were lying neatly outside on the pedestrian sidewalk. What does this prove?
The glass was broken from the inside
When glass is broken by an object thrown from the outside, the majority of the shards fall inward onto the floor. Shards lying entirely outside indicate the window was smashed from the inside out.
