Would it not be a symptom of the fatigue Americans are feeling? IRS political attacks, NSA/FBI snooping into phone records/Internet pings, Government deceiving/lying to it's own citizens, Government flooding the country with foreigners, No border/immigration enforcement...on and on.
Folks are afraid or at the very least at a heightened awareness that something is very wrong in this country.
I don't blame folks one bit. Keep vigilant.
Not to mention...all ferrule agencies from dept. of education to FDA arming themselves with military equipment.
