As a father of four kids, three boys and one daughter. If someone hurt them my first reaction would be to hurt the person that hurt them. But I realize that is not the right way to think. Most of the time the justice system works and sometimes it does't. I would probably wind up in more trouble than the person who hurt them.
I like other dad's here am probably more protective of my daughter than I probably should be but I think she feels safe knowing that if someone did hurt her that I would be there.
