Yes, it is scary for sure! I thought the whole thing was a hoax or I accidentally downloaded a virus or something until the map showed my location in our friends' driveway and it was spot on. I even double checked to make sure the GPS was off. It scares the heck out of me that kids have access to this type of thing and even the kids probably don't know it until they hear from a new 'friend', whether it's via phone, iPod, game system, etc. Scares me even more to think predators DO know how easy it is to reach kids this way.
I trust that LE and the FBI are probably completely on top of this possibility and I have no idea if it's even relevant to Dylan going missing, just seems like one possibility.
