I tell you, this is just the beginning. Not only Police will benefit from Facebook, but also governments. They will soon pay Facebook to profile and track their populations. Facebook will evolve into a single world’s population repository. It is just the matter of time. New-born kids will have profiles on Facebook. I have written more on this here.
Back to the point —
If you notice that one of your friends is feeling suicidal, you can report that. Facebook has released a special form, which you fill out to report users with suicidal Facebook status, images or other content. Facebook admins will review your submission and pass it on to Police. They will try to stop your friend from killing themselves. How sweet. Know anyone who’s bored with life? Report them through this form.
