In Philip K. Dick’s short story “The Minority Report” (and the subsequent film of the same name), futuristic pre-cogs — humans with the ability to see future events — were used to predict violent behaviors so police could stop them before they happened.
A shooting on August 4th at a Pittsburgh, PA fitness center killed three people and injured ten. Another chilling aspect of the story, however, is the Internet presence that the suspected shooter, George Sodini, left behind.
It is not far-fetched to think that a search program could be written to detect keywords and possibly flag such posts, creating a very real pre-crime tool. Go to Twitter and type in suicide and see what you get. The results can be quite surprising.
