This has nothing to do with the use of cell phones during school
hours. The reason I am in favor of kids using cell phones is for
their own safety. They may appear to be a foolish luxury, but they
really are life savers.
One day, in 1962, when I was walking home on 5th Street, I noticed
a man in a Ford Ranch Wagon driving by very slowly. Then I saw it
circling each consecutive block as I was walking home. Finally, I saw
it parked outside my house. In those days there were no safe houses
or block parents, let alone 911, so all I could do was duck and hide
until he was out of sight. If I had a cell phone I could have
notified the police, and that would have put my mind at ease.
