666 — the post of the devil.
I noticed that number also. In context it did seem ominous.
Vigilantes are not known for precision. It is the devil, trying to get everyone at each others throats.
Innocents would get swept in to the cycle. Things can blow up out of control (or surely would?). Obama would just love it, if someone tried. The actions of many, lead to incitement. If they can't get an perceived 'underclass' to riot, they can still feed grievance. Community organizers thrive on grievance, and let's face it, the liberal left is well organized.
So they keep pushing the envelope. It's like whatever "spirits" are driving them (just take a look at Angela Corey's face) WANT a reaction or over-reaction, they want isolated incidents of insurrection. They are poised to jump on that sort of thing with both big government and big media.
Then they can demonize those in opposition to virtual communism, further enslavement of the masses, with never having to admit that is what it is.
These are trying times...
