What Happens When a Civilian ‘Flips the Bird’ at the Police?

What percentage of citizens who have been ticketed by the police for a moving violation – particularly if they believe that they were wrongly charged – haven’t had the unbridled urge to curse at the (unnecessarily) smiling officer, or even deliver a gesture with a middle finger to express their displeasure? Probably the same percentage as major league ballplayers who get a called third strike when the pitch is way out of the strike zone. In other words, a large percentage.
