Lots of kids play near lots of things. That doesn't mean that they are "out of control."
Nothing in the article suggests that the child was "out of control."
The child was only five feet away, for crying out loud. The child was in no way out of control.
The post you're quoting does not say the child was out of control. It says he was not in his mothers control. You can't control what you aren't looking at.
