A jeweler reported that his store was robbed overnight. The front glass window was shattered inward, with hundreds of glass shards scattered across the hardwood floor inside the shop. The detective inspected the scene, shook his head, and arrested the jeweler for filing a false police report. What tipped off the detective?
The glass shards were inside the shop.
If a window is broken from the outside (by a thief throwing a brick or crashing in), the majority of the glass shards will land inside the room. Wait, if the shards are inside, that matches an outside break-in. Ah—if the glass shattered *inward*, the force came from the outside. But what if the glass shards were on the *outside* sidewalk? If someone breaks a window from the inside to fake a robbery, the glass falls outward onto the street. The jeweler claimed the glass was scattered inside, which actually matches an outside break-in. Let's rephrase: The glass shards were scattered across the *sidewalk outside* the shop, yet the jeweler claimed the thief broke it from the outside. If the thief broke it from the outside, glass falls inward.
