Five points.
First, no where in the article was speeding in a school zone mentioned.
Second, under current code interpretation a motorist must come to "a complete rest" for at least two seconds before proceeding through a stop sign or it is a legally rebutable presumption that the motorist "ran the stop sign". Many Californians violate this interpretation of the code section, even at busy intersections and are not cited.
Third, the article did mention that the woman obeyed a traffic light during the "pursuit".
Fourth, the article mentioned that the woman reasoned that the citation could have been as easily administered at the school as at the point of first offense. A reasonable conclusion.
Last, no where does the article state that the motorist was speeding after the initial stop.
The woman's poor judgement with regard to public property (the citation book) and her definace of authority certainly warrented careful examination but hauling her off to jail was an obuse of authority under color.
Fleeing the police is enough to get anybody hauled down to the station. And that's the way it ought to be.
