Unfortunately, Obama is a psychopath (I mean that in the true clinical sense of the term). His arrogance is not the problem per se, it is only one manifestation of his pathology. We can't assume that logic and a reasonable grasp of the situation will guide his actions in a practical direction.
Yes, but even the most insane would-be dictator needs a massive, and utterly obedient force to wrest complete and total control of a nation. It also requires an unarmed and cowed populace to achieve complete success.
Obama has neither of those things. He doesn't command complete loyalty within the government or military, either.
Without at least two of those three conditions in his favor, he doesn't stand a chance. Any dictator worth his salt would tell him that.
how many people just surrendered when the police unilaterally declared confiscation? no law. no court order. they just took.
how many? It was just the law abiding that disarmed willingly.
