All of the officers in my department swore an oath to uphold and defend the Constitutions of the United States, and the State of Wyoming. As I pointed out in an earlier thread, most are also military veterans, and still feel bound by that oath as well.
If there were any that did not take it seriously, they didn't last long because I never met them.
I know of at least two officers who were reprimanded for refusing to carry out instructions because they were of the opinion, that the instructions violated either their oath or their sense of morality.
It should also be pointed out that peace officers do not have either the authority or responsibly to administer, write, or interpret the law. That authority was given by the constitution to the legislative, and judicial branches of government. The actions of the legislative and/or judicial must be flagrantly
in in violation of the oath before the officer takes it upon himself to do someone else's constitutionally created job and make/interpret law.
When an order is flagrantly, and blatantly unconstitutional, most (99 percent) of the officers I have known and worked with would simply refuse to obey.
I would imagine that in some places like the NE and West Coast megalopolises, there are many who will blindly obey, but I certainly hope that even in NYC or 'Fisco, a majority would stand by their oath.
Calling a person from any occupation into a mandatory meeting and telling him/her to do something is one thing. Getting them to actually do it, is quite often another matter altogether.
