Any attempt at what you are implying would just be another Waco, Ruby Ridge, or OKC
And that's exactly how everyone will se it....
As for co-conspirators...
99.9% of the retired active duty military would be out
Probably about 98% of the former/present LEOs
So that leaves the guys who think they're up to infantry skill level on their own, with no practical experience outside of tactical-training courses....
Oh, btw, those 'ameturs' in the ME arent causing as much carnage as the media would like you to believe, they have a currently limitless recruit pool, and they have no qualms about attacking civillians...
Finally, in your little fictional scenario, what justification would you have for your carnage... You see, if you are going to attempt such things you have to work out the politics beforehand - otherwise you will be seen as Koresh, Weaver, or McVeigh - And BTW, most of the country sees those 3 as a suicidal cult leader, a criminal, and a terrorist.
So think about that....
As I've said before, any 'take it back revolution' wouldn't last a week - you'd loose, and everyone even remotely involved would be villified for the rest of their lives....
Remember that every time someone repeats 'from the rooftops' or whatever...
If that's your idea of voting, be prepared to lose the election. We live in a revolution-proof nation - it's been that way since the 1860s, if not before...
