Ah, "Agents provocateurs." Aka ultra- liberal morons' favorite excuse to try and dismiss the psycho radicals on their side that engage in violence and lawlessness.
Meanwhile, in real life, it is well- documented that many liberal groups (Including DUmmies) have attempted to "infiltrate" Tea Party demonstrations waving racist signs in a pathetic attempt to frame the Tea Partiers for racism.
One advantage to the liberal freaks' crying about "Agents provocateurs" is that, similar to the incessant "Troll/ mole" hunts the DUmmies go on, it causes a great deal of hilarious paranoia and dissension in the ranks to develop among the Occupiers, as they begin accusing anyone and everyone of being a traitor. When they can't even trust each other, they fall apart even faster than normal.
