I thought of the classic ending of the 1978 Invasion of the Body Snatchers when I watched the pointing at the Breitbart crew:

• Brandon Darby gets verbally attacked at a July 21,2013 Trayvon rally organized by the New Black Panther Party and Quanell X. The Occupy contingent recognized Darby while he was on assignment for Breitbart News. (Via Breitbart)
