Interesting.
I wonder if it's in October that the USSC will issue out a ruling holding ObamaCare to be a-ok. That would stir civil discontent.
(Though that's supposed to be ruled-on and released this week.)
Another fun one would be Fast And Furious; if it got out into the general public, with the full understanding of a) just how many government organizations had to be involved, and b) that it is nothing less than state sponsored terrorism. That too could have an effect.
More likely than either of those, I think, is the unveiling of "Surrender your Sovereignty" treaties, or perhaps the seizing of people's 401Ks.
Do you have anything in specific that these police/firemen were told/saying?
