Protestors wearing Guy Fawkes masks participate in a demonstration against the Anti-Counterfeiting Trade Agreement (ACTA) in Berlin February 25, 2012. Protesters fear that ACTA, which aims to cut trademark theft and other online piracy, will curtail freedom of expression, curb their freedom to download movies and music for free and encourage Internet surveillance. The banner reads "People". REUTERS/Tobias Schwarz (GERMANY - Tags: POLITICS CIVIL UNREST)
