There is a large difference between not following a confiscation order and actively siding with the populace. I agree that some police forces might be inclined to sit it out, but I'm still sure that there will be no shortage of JBTs more than willing to murder their fellow citizens for resisting the government's unconstitutional actions. After all with 0's newly announced drone policy summary executions have now become standard policy. Who needs due process? An outmoded concept from that living document - the constitution.
You need not go further than the police state that was New Orleans post-Katrina for examples of rogue cops from all across the country wantonly violating the rights of US citizens.
What is now? Fifteen such cops have been successfully prosecuted for murder?
That statistic begs the question of how many more SHOULD BE?
