This question already has an answer here:
I refer to a shot that occurs quite often in crime shows...
There is the victim at the hub and spokes of red yarn that connect the suspects. How realistic is this in modern detective work?
I have read these articles:
- Decoding The Detective's 'Crazy Wall'
- Do detectives really pin a bunch of pictures on a board when investigating a crime?
- What is the name of the evidence board used by Detectives?
- Does this investigative process have a name?
All of which suggest in a vague and noncommittal way that this technique is more about narrative exposition for the television viewer rather than a detective's tool. Can someone confirm and explain?
