Americans need to be very vigilant: Obama and his loathsome WH staff are very calculated in their use of power. As dissent among the populace grows, they are capable of plotting staged events to boost their advantage.
If these arch-manipulators perceive there isnt measurable fear in the hearts of the people, they will create that fear to solidify their power. They know people will succumb to fear, and will relinquish their God-given liberties when they are fearful.
And the rest of us an excuse to shoot back.
