The assault on Cliven Bundy's ranch, the assault on the Branch Dividian compound, and the assault on the Weaver's property are extreme examples of a situation that is so common we all experience it. Every law is enforced through the threat of violence.
Don't obey the law, then you get arrested or pay a fine. Those who refuse are either fired at on the spot, tased (those who have heart conditions are at extreme risk from electrocution), or a team of mall ninjas armed with weapons of war bust into their home at night, generally trigger happy enough to fire at anyone even remotely perceived as a "threat." Even minor infractions are ultimately backed up by a class of people whose sole job is to inflict harm on whatever is deemed to be a "threat," whether that "threat" is an unarmed elderly, or a small dog, or a real criminal.
What is law exactly? It is supposed to be a code of conduct to ensure civilized discourse in a group of people, so that no one may be deprived of rights, property or their own bodies. Today, that is called natural law.
Unfortunately, the term "law" can be rationalized to mean anything, just as "freedom" is. Think about it: many on the left see freedom as freedom from debt, poverty, uncertainty, and ultimately responsibility. Well, law has been twisted the same way. Instead of being a neutral set of rules, it has become the lethal enforcement of a group's moral view. The prevailing moral view around the world is that everyone's behavior must be regulated, and their property annexed (wealth is property too) to serve a common good. This view is not just restricted to Marxism. Fascists believe the state comes first. The majority of Muslims believe Allah comes first. Across the political spectrum are those who would censor the arts, believing that "decency" comes first.
This social contract fails because not everyone has equal needs and not everyone is altruistic. Unfortunately, this fact is not lost on those who believe that the common good comes first, and the solution is to use violence. Ranchers and "sustainable" power require a lot of space. Solar power, as feeable as it is compared to more traditional power, brings in more revenue than a single family ranch. From the view of the environmentalists, the Earth has more rights than people. So the troops march in.
Even natural law needs to be enforced from the barrel of a gun. That is why we have a 2nd Amendment. The only question is, are we so indoctrinated into servitude that we won't use it? The ending of the siege on Bundy's ranch gives hope that we are not.
