It depends on how big the park is. When children are in public, parents should be the ones protecting them. Some children's parks are huge. And loaded with people. I have no idea about the park in the article. When we go to a park, we have a buddy system for the bigger children. And the little ones must be watched at all times. I don't expect the police to walk around watching folks to see if they are accompanied by at least one child.

Parents watching their own children? Older children using the buddy system?

That makes too much sense, and requires no government intervention! It will never work!
