While browsing for Visio Shapes, I came across this: The Visio Crime Scene Template:
At first I thought - "Oh - that's just some crazy joke thing - but no, it turns out that people actually use Visio for recording evidence like this. (When you think about it, it makes sense - Visio's ability to do scale drawings is great, so it would lend itself to this sort of thing pretty well.)
But still, a little creepy. There are twenty different murder weapons, including a meat cleaver and screwdriver. ... ew.
Now what I want to see on CSI is someone yelling at their terminal: "No! I didn't want to rotate the shape! I wanted to resize it! Grrr..."
