global elite using school shootings to disarm the population…

Read "Behold a Pale Horse". This isn't a new concept

The government encouraged the manufacture and importation of military firearms for the criminals to use. This is intended to foster a feeling of insecurity, which would lead the American people to voluntarily disarm themselves by passing laws against firearms. Using drugs and hypnosis on mental patients in a process called Orion, the CIA inculcated the desire in these people to open fire on schoolyards and thus inflame the antigun lobby. This plan is well under way, and so far is working perfectly. The middle class is begging the government to do away with the 2nd amendment.

There is also this quote attributed to the book. I'm not sure which page, and that pdf file does not have OCR on many scanned pages.

Some of Cooper’s best‐known predictions appear in Behold a Pale Horse, which runs a densely typed 500 pages. Eight years before the Trench Coat Mafia murders at Columbine High School, Cooper wrote: “The sharp increase of prescriptions of psychoactive drugs like Prozac and Ritalin to younger and younger children will inevitably lead to a rash of horrific school shootings.” These incidents, he said, “will be used by elements of the federal government as an excuse to infringe upon the citizenry’s Second Amendment rights.”

It's easier to enact tyranny to subvert and control a population and remove all their rights when they are unarmed and can not fight back.

When you strip rights quickly and suddenly an armed population might revolt. If they have weapons of equal force it is not so easy. At the time the US Constitution was drafted, you had pistols, rifles, and canon. This put militias on near equal footing to that of regiment military with the exception of numbers, training, and canon.

The US Founding Fathers could not have anticipated how large the force disparity would become over two centuries later. The general citizenry still have access to pistols and rifles while the military have machine guns, planes, tanks, bombs, lasers, ADS and many other weapons.

It's not even close anymore, but still the political class and aristocracy know that as long as a population have weapons, they can not so easily remove average people from society.

That isn't stopping them from conditioning populations to accept slow erosion of rights over successive generations, or the latest tricks involving "pandemics" to isolate and control people under the guise of safety.

These included the disclosure that “the CIA and the military are bringing drugs into the United States to finance their black projects.” Cooper also predicted that “the rape of the Savings and Loans by the CIA is only the tip of the iceberg. At least 600 banks will go under in the next two years.” The current monetary structure, Cooper said, “will be replaced by a cashless system that will allow the government to monitor our every action by computer. If you attempt to stay out of the system you will not be allowed to buy, sell, work, get medical care, or anything else we all take for granted.”
