Show idea: How Much Crime Scene Evidence Is In Your Home. Have a forensic team process several "regular" homes as if they were crimes scenes. Is there enough "evidence" that could convict someone of a crime. If police went into your home today, unannounced and processed the home would they find "suspicious" blood, blood splatter, missing items, broken items, that would indicate a crime? Freshly cleaned areas, freshly painted walls, replaced carpets, areas around the property that have been freshly dug, or blood in a vehicle?
Many times on your crime shows we see that murderers are convicted on circumstantial evidence. Tiny amounts of blood, or luminal results. What does a regular home show the police?
