The problem I see with believing the police are above reproach and should always be obeyed no matter what is that this leads to a very draconian and unsafe situation. I should state, by unsafe, I mean for most of the population. For the ruling class (and you are a fool if you think the ruling class in America is the politicians) and the enforcers(the police), it is a safe and desirable situation whereas they enjoy lording it over all others.
This situation is very much starting to look like shogunate era Japan, IMHO. You have the ruling class Shogunates (The 1%) and the Samurai (Police) who have life and death authority with near no penalty for dealing out death (to the civilian population), even with the lack of questioning as to why.
You see, Shogun era Japan is often romanticized, and Samurai seen as noble defenders of order. The actuality is that they were appointed thugs that kept the population obedient not through skill of arms and bravery, but through acts of terror and constant oppression. To be frank, they could kill any civilian with impunity, and not need any justification.
This is the trend police in America are following, IMHO. They need only a flimsy justification, and some in the legal system seem apologetic they even need to justify their use of lethal force, that their actions, by law, need such a flimsy defense at all. (Look at the Trayvon Martin case. The judge, after the acquittal, actually apologized to Zimmerman that he had to endure the indignity of a trial,(Thus showing conflict of interest) and gave him back his pistol IN COURT) They are not completely there yet, but on their way. Good cops are fired or reassigned to desk jobs, and the thugs get put in the field and promoted to positions of greater authority. Hell, precincts seem to reward cops for bad behavior.
Example...Cop arrests another off duty cop for speeding at speeds over 120 mph, and endangering those in traffic. Her reward? Harassment, and reassignment to a desk job. Has a 500,000 lawsuit in court. Will have to wait and see if she wins the suit.

So the action to take for a good cop that slipped in the system? Desk job.
So no, I think the authority afforded cops needs to be reigned in, or we will live in an orderly, controlled hell like those that lived in Imperial Japan. Most of us will, at least.
