There could be a couple triggers to Lexington and Concord 2.0

1. The economy (Austerity measures bringing resistance like Greece and then general lawlessness)
2. The 2012 election (re: 1860 election)
3. Gun grab 1775 style
4. Mexican Drug War creating a de facto war zone in American S.W. strengthening militias there which grow enough to actually rebel
5. We stop talking shit and do something about this shit hole fascist state
