This is another COINTELPRO-style attempt to take the focus of Occupy away from the Wall Street criminals behind the mortgage-0backed securities fraud that cost this nation $545 trillion, and send Occupy down another blind alley. Over at another venue, planted shills are trying to steer the Occupy movement onto the global warming debate (even as snow falls all around them.) Occupy Phoenix was hit with planted brochures asking "When is it okay to shoot a cop", a modern day replay of the infamous "Black Panther Coloring Book" created by the FBI back in the 1960s to derail the civil rights movement.
The other side loves to play dirty.
These attempts to shift the focus of the Occupy movement are bought-and-paid for propaganda tricks. In this case, this stunt gives the media the excuse to dismiss the occupy movement as a bunch of druggie hippies.
