I’m not sure “unpleasant” is how I would describe it. “Natural” might be more accurate.
The entire idea of the law is based on the idea of preventing blood feuds and vendettas through fair arbitration by someone more powerful than either side. However, if government does not fairly arbitrate, taking the side of a criminal or civil oppressor against the public, or even supporting them, the social contract has been broken, and the old rules come to the fore.
At least twice now, at Waco and Ruby Ridge, and truthfully much more than that, government has been seen by the public as tyrannical and oppressive, not unbiased, fair, or even concerned with legal recourse instead of massacre and brutality. And then, cynically vindicating those who carried out such abuses, and even promoting them for their offenses.
Even if some individuals, like Timothy McVeigh, respond in kind quickly to such acts, the public as a whole just watches and remembers, and while they are much slower to anger, the anger is there.
As with vigilante organizations, the public as a whole tries to remain non-violent until they are pushed to their limit. Arrogant tyrants in government always figure that they can arm enough of their government to put down the public; and more so, they figure they can purge their military and police of those who will not mindlessly oppress the public.
But this is a grave error on their part, because the military and the police are members of the public, and while some of them may be willing to turn their guns on civilians, there will always be many more who not only will not, but will turn their guns on those doing so.
When this happens, shortly thereafter, tyrannical politicians and bureaucrats find themselves hanging from light poles, often at the hands of those they thought were loyal to them. The public, as such, doesn’t even need to dirty its hands.
