It's a difficult question and there are no easy answers. On the other hand, if we fail to address this issue at an early age, we unintentionally make potential victims of our children. Both child and parents escape unscathed and wiser for the experience. In other cases, the incident ends in tragedy. We live in an enigmatic world.
People tend to be either too trusting or too paranoid.
We don't want our children providing easy targets for predators yet, we don't want them growing up in an air of fear and suspicion. I don't have all the answers. I'm just a dumb old ex-cop. I'm also a thirty-one year practitioner of the Martial Arts. I firmly believe that planning and mental preparation can and does make a difference in a society full of predators.
