Motif-like repeated mention of the Constitution, currency, mind control, the two wars...and then a whole lot of nonsense mixed in. Where have we seen this similar brew before? Take a look at an earlier post on another "lone wolf assassin," as our security establishment likes to name them, John Patrick Bedell. You will see some of the same characteristics.
I will go out on a limb on this and say we can see this as a strategy not a coincidence. A strategy by those who wish to eliminate the last bastions of critical thought from American society. If they can convince the average person that critical thinking about the corruption of our country is nothing more then a prelude to a dangerous rampage by a mad individual, the propaganda succeeds. Most will watch 60 Minutes episodes or other mainstream news shows delve into the "mind of the assassin" and find out it sounds a bit like that 9/11 Truther they know, or that guy that doesn't like the Federal Reserve. Maybe it sounds like that Ron Paul supporter they know, or some liberal who is unhappy with the direction of the country.
There is already some evidence of this being a manufactured atrocity. Have a look at previous posts if you haven't already.
