Dear Harlan Coben
Don’t be silly. Kids tend to be smarter than their parents think they are. If you put spyware on your children’s computers, two things will happen. One, they will detect it—and perhaps put malware on your machine. Two, they will resent your intrusion for the rest of their lives.
Sure, I understand your desire to protect them. But before thinking of the damage the rest of the world might do to them, think of the damage you would cause by betraying their trust.
