The girls had a simple choice. Help a lost child find their mother or torment her. They went with torment.
I have no clue what the mother was doing and she should be held responsible for not watching her child but these two girls should have had their asses beaten publicly and then done a few hundred hours of community service after about thirty days in jail.
Blaming the mother doesn't get these two pieces of garbage off the hook any more than blaming a rape victim for their style of dressing excuses a rapist.
Lost? They were all in the McDonald’s playscape area. McDonald’s posts signs stating children must be supervised by their parents. Mom failed the child.
