Since the start of the Occupy Wall Street protest on Saturday, at least five people have been cited for violating a little-known New York law that bans masks at gatherings of two or more people unless it's "a masquerade party or like entertainment." Carnival-style fun isn't exactly the point at the financial district demonstrations, albeit exact goals are still pretty undefined. Nonetheless, demonstrators are now "acutely aware" of the obscure statute, which dates back to uprisings in 1845, when the price of wheat dipped:
After [landowner Stephen Van Rensselaer IV] moved to evict tenants, disgruntled farmers disguised themselves as "Indians," dressed in "calico gowns and leather masks" and attacked agents of the landlords. The court papers said the tactics adopted by these rebel groups ranged from "tarring and feathering" to murder, including a sheriff.
Things are calmer down on Wall Street these days, where members of the so-called "hacktivist" collective Anonymous are donning their signature (and accidentally corporate) Guy Fawkes masks (see here and here) and tweeting at one another. One protestor was also charged with "damage to the sidewalk" for writing a Gandhi quote in chalk on the ground.
