Czech protesters are taking to the streets on occasion of a European day of demonstrations against the international Anti-Counterfeiting Trade Agreement (ACTA). Protests are set to begin in Prague in the afternoon. Among the organizers of the demonstrations in the Czech capital is the group Anonymous, which opposes internet censorship. The controversial international agreement has come under fire from both internet users and officials. Some believe that it will pave the way for regulations that may censor content available on the internet and infringe upon freedom of expression online.
