Frank.
My only question is, are they going to tell you if your kid has come up missing?
Can you imagine a school administrator calling you to say your child is lost?
I find it much more likely that they will first double check the school, then check the system, then alert the authorities. By now child has been missing for 60-90 minutes, and the only way the parent will find out is from the 6 o'clock news
Not a pretty situation.
I just can't picture them going into high gear as soon as the kid comes up missing, because most people in CommieFornia (where this is happening) will be under the following delusion:
He's wearing a tag, so he must be safe, right?
Yup, must be cutting class or something.
He's not in the school. We checked.
Okay, double check the system, it must be acting up.
Okay, checked each sensor, all good, and the base station.
Guess we should call the police now.
911 has us on hold.
You get the idea. Kid has been missing a minimum of an hour before someone decides to act.
This is just the way I see it going down.
