Yesterday at 4:30am I got a call from the Scottsdale PD asking us to check to make sure that all the kids are home (don't have kids) as they found a little boy nearby. It was an automated system that called some 10,000 residents in the area (caller ID showed "emergency message", freaked me out in the beginning), all at the same time. Nice going, I hope the kid was returned to his home safely.
