Sorry, the Feds started with the killing of innocent women and children first. Guerrilla war is guerrilla war. Turnabout is fair play. I have no sympathy for those that act like criminals under the color of Law.
This is not a schoolyard fight between short-tempered six-year-olds, caught in the act and finger-ponting at each other saying: "HE started it!"
Mature adults have no sympathy for the short-sighted who use "moral equivalency" to justify suicide by cop. Nor for those who, badge or no badge, would kill innocent family members to teach a lesson to resisters OR to law enforcement.
Don't be in such a hurry to discard the protections of a civilized society, as created by the Founding Fathers, for the temporary emotional indulgence of quite unnecessary revolution. "Me want what me want and me want it NOW!" is not an expression of conservatism but rather resembles the New Left that many of us successfully fought in yesteryear.
There are many legal avenues of redress of grievances that have not been exhausted and would have to be exhausted if you expect to broaden your resistance to folks who don't see seizing a federal wildlife center as a hill to die on.
