They're looking for an excuse for gun control, martial law, etc.
Those 3 WM were probably set up in some way, just like many of the other recent fαℓѕє fℓαg attacks (including Oklahoma City bombings).
Think about it what this phrase means for a minute: "Plans to kill Obama".
Did they draw little stick figures and cartoons of them with rifles pointed at Obama? As if a murder needs "detailed plans". I think a smart person would just memorize the "plans" so the evidence would just be a couple of rifles ("We're going hunting this weekend!").
You see, it doesn't add up -- but how many people have their brains turned on these days?
It reminds me of 9/11 -- they found copies of the Koran in the trunks of the so-called hijackers, etc. How simple-minded can you get? It's so OBVIOUS what they're doing, but the majority of people buy right into it!
It's gotta be "too much TV".
