I watched this in real time... (Score 5, Interesting)

...from the initial post about the car being stolen, to posts from various members sighting the car, to the eventual arrest video and hilarious photochops to go along with it all. At one point, there were 400 members and 5000 guests viewing the thread. Every refresh would bring up 5-10 more posts instantly. This wasn't so much a case of internet vigilantism. The thief had literally been spotted driving like an idiot by multiple members of that board - before the post was even made. At that point people started chiming in with "holy hell, i saw that guy too, he was driving 90 down a residential street near ". All of these sightings eventually led to a sighting right outside the guy's own home... case closed. I highly suggest logging into beyond.ca and reading the thread, there is some serious photoshop comedy gold in there.
