From assembly to free speech, the Occupy Movement has become one of the most all-embracing and polarizing exercises of First Amendment rights that our country has seen. Cartoonists have been among the many voices chiming in and being arrested for participating in Occupy protests across the nation. Cartoon Movement has compiled a sketchbook of images, including images from journalist and cartoonist Susie Cagle, who was arrested at Occupy Oakland. Sharon Rosenzweig and Shannon Wheeler also contributed to the sketchbook, which Cartoon Movement plans to update weekly. You can view the Occupy Sketchbook here.
