What makes you think you have to kill people? Why not just sink their yachts, burn their planes and homes? Dox them. Shut down airports with drones -- nationally. Burn their warehouses, datacenters, factories. Hack their computers and steal their money. Etc... etc...
Americans are so indoctrinated that they think killing is the natural next progression of peaceful protests.
Humiliating them is much more damaging to their stupid movement.
And why wouldn't they? It's not like votes are going to matter anymore.
