The Thomas Jefferson Center for the Protection of Free Expression releases its yearly "Jefferson Muzzles," which (dis)honor the most egregious examples of the suppression or attempted suppression of free speech.
Notable examples include Rep. Alan Grayson (D-FL), for "urging the U.S. Attorney General to seek a monetary fine and a 5 year prison sentence against a vocal critic for alleged violations of Federal Election law that, even if true, represent minor transgressions" and Chicago Alderman James A. Balcer for "claiming the authority to destroy a work of art based on his personal assessment of the work’s content."
