I don't think it's a trap mainly because I don't understand how it could be used as a trap unless the perp returns to the crime scene (red dots most likely) and tries to destroy evidence. Just going to the page or clicking on the map doesn't make you guilty obviously, just curious. People from this page clicked, and of course I had to click to see what they were talking about with the dots not working. The simplicity could be to conserve bandwidth. I don't think it's an empty gesture, either. Perhaps some people might feel more comfortable texting vs calling.
