If you where in the position to need it you might find your decision to not utilize it to be endlessly horrible.
It was a choice. I chose to let them risk life and limb doing whatever stupid shit kids do behind their parents’ backs, risk being run over by a car or kidnapped as they walked to school. The risk was very small, and the benefits of letting them grow up with a normal, non-Orwellian childhood far outweighed them. Hell, my generation and those before me grew up like that and survived just fine.
But I agree: if something really bad had happened, I don’t know how I could have lived with myself. And this always weighed heavily on my mind whenever they were late to come home.
