I don't think they would.
I don't believe there is a third of the population who can spell "totalitarianism," much less know what it is. I think the majority of people living in the West don't even know what kind of government they live under ... even worse, I believe they no longer even care.
The most incredible thing about this event was just how little uproar there was about it, other than full support for whatever it is the "guffamint" decided arbitrarily to do. The media was on the sidelines cheerleading the whole thing and built up an even bigger set of vague smear stories than they did against David Koresh after they incinerated him and eighty people. The thing is, David Koresh was a bastard and some of the agitprop was likely true, except that still doesn't explain why the government attacked a civilian home with heavy armored vehicles and assault choppers. Whatever was wrong with Koresh, he had a twenty year history of cooporation with law enforcement.
Waco was a field trial and this recent experiment at the Zion Ranch was an attempt to extend the envelope that was already pushed out by Waco and Ruby Ridge.
Next up, the government will be conducting field executions of people with overdue library books. People who pass without signaling. People who play their music too loud on Sundays. Whatever fringe group you got, the government will use them as their excuse to see how much more they can get away with. Each time, the population is further desensitized to atrocities by the ruling elites.
So don't come crying to me when you feel that rifle barrel in your back shoving you into the boxcar. You waited too long to start caring and it was too late by the time you did.
