We simply don't know ALL the details and circumstances. Was she really in sight of the vehicle? Exactly how long was she away? What else was in the vehicle with the child? (i.e. big ol' bag of pesticide behind her) Then you lump in the fact she was probably arrogant and cocky to the Officer on scene. Oh, BTW, you don't have to answer incriminating questions, BUT you must answer basic questions like your name, your child's name, your address, your phone number. I have threw several people in jail because they thought that they didn't have to answer those simple questions.
