Anonymous: hero or terrorist group?

There is a special group that some people don't know about called "Anonymous." They are a special group of hackers that state they fight for freedom, but the means are a little unusual and extreme. some of "accomplishments" have been attacks on certain censoring groups. One attack was against the company Sony Entertainment for the arrest of three hackers that according to them,"free speech." Another Attack is when they attacked ACTA and shut down many of their important sites and have 3 EU countries back from the plan. One last major attack is when they shut down an official CIA website for about an hour. These attacks show just how powerful they can be, but are they doing it for the right reasons? Everyone for freedom can only hope so.
