A priceless diamond was stolen from a glass display case. The security guard swore nobody entered the room, yet the glass was shattered inward, with hundreds of tiny sharp shards scattered neatly across the velvet pedestal inside the case. Detective Cruz smiled and charged the guard with insurance fraud. Why?
The guard broke the glass from the inside
If glass is shattered inward (into the case), the force came from outside the case. However, if the shards are scattered *inside* the case on top of the pedestal, it means the glass was pushed from the inside out, or the guard staged the break-in from within and dropped shards inward.
