Read the reactions of the protestors to being thrown out. The protestors are actually wimps.
Social justice activists are ALWAYS wimps.
Thats why PETA goes after little old ladies in fur coats, and not Hells Angels in their biker leather.
Also why the IMF/World Bank protests in DC have been pretty sedate these last several years. After some minor rioting one year, the DC cops decided to haul the malcontents they arrested down to lockup in Anacostia rather than the usual 2nd District tank (a few blocks down from National Cathedral). The punks got the message and decided it was in their best interests to settle down.
I saw that.
