FLOWER MOUND, TX (UPI) - A 10-year-old girl was arrested and charged for fighting in a park with her 13-year-old sister... The older sister said the fight broke out after her younger sister refused to follow her instructions... "'This is criminal, and one of them is going to have to go to jail and it's probably going to have to be your younger one because she was the aggressor,'" their mother quoted the police officer as saying. "And I said, 'Are you kidding me?' and he said, 'No, no.'"
