Being a member of a particular group doesn't mean that they will disobey orders when their means of putting food on the table may be on the line.
Maybe...
But that particular sentiment is the primary reason that Oath Keepers came into being.
Would LEO's choose enmasse to disobey orders to disarm the public? I have no clue. It'd be a darn tough choice for them as individuals.
In the military new boots all the way up to the commanding general/admiral of a service are taught that there is no duty to obey an unlawful order. We were also taught that if you choose to disobey an order, whether lawful or not, that you will almost with certainty be court martialed. One had better be darn sure the disobeyed order was unlawful.
LEO's are in a very similar situation.
It will take men of great courage and high moral fiber to stand up and say no.
