This is very much the crux of it.
Back during the immediate post-9/11 era there was a huge push to restrict all kinds of civil liberties (and the birth of today's surveillance state) in the name of preventing the next terror attack, which could be "a mushroom cloud" in the words of George W. Bush.
There's a problem with this reasoning.
Osama bin Laden wasn't some random dude who got radicalized. He was a member of one of the wealthiest families in the world. He was born rich, grew up rich, attended Harvard, and had a family that rubbed shoulders with heads of state and were directly connected to the Saudi royal family.
Osama bin Laden was a member of what I've heard described as the "superclass," those who are beyond just being "merely rich" in that they possess not only vast wealth but internationally diversified wealth and powerful political connections.
He was of the social class that is behind the glass of a surveillance state, and if he wanted to avoid any possibility of surveillance himself he and other members of his class could easily afford expensive security consultants and specialized devices. They could also afford armies of attorneys to get them off any lists and out of any trouble.
If someone detonates an atomic bomb in Washington DC, it will not be some random middle class youth who got radicalized on a 'chan board or a Facebook group. It will not be some random protestor or dissident. It will be someone like Osama bin Laden. It will be someone with the money, expertise, connections, and background to find, recruit, and pay the personnel required to obtain or build a nuclear device. It will be someone with the connections to organize the logistics to smuggle it into the country and put it in position.
It will be a member of the global elite.
People with bin Laden's level of wealth and privilege are the dangerous ones. The lens of scrutiny should be aimed at them. One member of the middle class radicalized with toxic ideology might shoot up a school, but one elite radicalized with the same ideology could blow up a city or engineer a super-plague.
