Child abuse/neglect

Would you have called the police in such a situation? Why or why not?
Do you agree with how the mother (Cory Widen) reacted? Why or why not? If you were in her place, how would you react?
The article mentions another mother (Kim Brooks) who left her son in a car for a few minutes on a cool day to run an errand. Do you think it was right that she had to take parenting classes and complete community service? Why or why not?
Should there be a law regarding such situations, stating at what age children should be allowed to do various things? Or should it be left up to each parent to decide? Give a specific reason for your answer.
Other than child abuse/neglect, if you had to pick one area/type of crime that police should be focusing on, what would it be and why?
