The protest is following the Weather Underground playbook.
The WU figured out a long time ago they screwed up in the 60’s and 70’s because they didn't use foreign terrorist to carry out the attacks.
The terrorist attacks carried out by the WU were considered as nothing more than criminal acts.
Since the first WTC attack in 1993, the left has tried to make it appear as if some radical group has teamed up with the terrorist.
They haven't limited it to just one group. They have tried with different terrorist attacks, to make it appear as if Radical Blacks, White Right Wing Extremist, and radical illegals have teamed with the terrorist.
Go back and review the lefts talking points about the Tea Party and how violent it was in the weeks leading up to the car bomb that fizzled in NYC a couple of years ago. The left claimed the Tea Pare was a bunch of Tim McVeigh wanna bees.
The talking points of the left prior to the attempted attack, matched the bomb the terrorist used, a fertilizer bomb.
