You are required to obey the traffic laws for good reasons. Sociopaths like Sandra Bland think that all of the public roads are their personal private property.
There is nothing about Bland's behavior that suggests she might be sociopathic. She was in a hyper-emotional frame of mind at the time which could be attributed to any number of events in her life. So I believe when such individuals are observed violating traffic laws by police they should be issued warnings or citations and not provoked into behaving in a manner which might subject them to arrest.
American police officers are equipped with an arsenal of procedural rules, regulations and laws which enable them to arrest an ordinary individual for behavior associated with the most minor infractions of administrative or traffic codes. Unfortunately there are many (too many) cops who are well-versed in methods of applying this web of insidious petit mandates to the purpose of coercing submissive behavior from citizens who qualify for punitive citation.
Most people who are stopped for traffic infractions are perfectly willing to behave submissively, even sycophantically, toward the officer to avoid avoid being cited, others, for one reason or other, are not. While their behavior toward the officer is less than abusive it might reflect annoyance and/or agitation. So the arising question is whether it serves the interests of society more for the officer to assert his authority on such an individual for the purpose of commanding respect for his official status, or for him to focus on the purpose of the stop, ignore the offensive attitude of the driver, issue the citation, and be on his way.
I believe the Sandra Bland example speaks for itself. In this example the officer could easily have ignored her offensive attitude, issued a warning or a citation and resumed patrol. But he chose to transact provocatively with an already agitated woman, whom he ended up arresting, and who committed suicide in jail, causing him to be suspended, unnecessarily calling negative attention to his agency and quite possibly prompting a costly lawsuit.
But in spite of the negative outcome of this traffic stop the vast majority of cops will insist that Trooper Encinio handled it properly.
