First of all, it's not a serious attack plan, and everyone knows it. They've already released the date (giving the Feds time to hide anything of value and fortify for the attack, and identify, track and marginalize all of the 400,000 people who have identified themselves as potential subversives) and make mention of "Naruto running" faster than bullets (physically impossible).
Second, if the U.S. government ever decides to commit mass slaughter of thousands of its own citizens solely because it values secrets over its own people, that will be grounds for the worst and bloodiest revolution this country has ever seen.
It is a call to incite a mob to defy the law.
That, frankly,
is insurrection, but even more disturbing is the idea that we can shed the bounds of civility if there is just a big enough mob, and over the most odd reasons.
What's next? Storming strategic missile silos? Naval bases? The Pentagon? CIA Headquarters? Fort Knox? Oil refineries? Nuclear Power Plants? There is a long list of relatively 'soft' targets which are relatively secure and safe as long as there are not scores of idiots running around virtue signalling, and that does not even include the likelihood that there will be people in that crowd who definitely have interests contrary to our nation. Just a bunch of nitwits breaking things, effing with controls, and damaging critical systems could well lead to disasters that will have serious potential to harm everyone, ultimately, from the people who work and live in the area, to consumers of products at the gas pump. Destruction and theft of research data which might give this country an edge in the next conflict harms us all.
Granted, some of this BS idea was established with the responses to the Fergusson and Baltimore riots, (I said then just wait until other people decide they have "equal rights", too.) and the tacit Obama Administration sanction of the sh*show over the Dakota Access Pipeline, but establishing the concept that a large enough
crowd mob means no defense of facilities or the law can be mounted might lead to other even less desirable things. The Oktober Revolution was one such, the SA storming the streets in Germany another. It is dangerous precedent.
Still, a couple of air tractors loaded with nonlethal irritants could well break the back of such an operation without having to engage anyone with lethal force unless relatively small groups manage to circumvent that.
