It's an anti-terrorism act; the only thing it would truly do, is allow indefinite detention of citizens, which is essentially just the Patriot Act. Anonymous is right about 90% of the time, but they try to embellish things just for the sake of civil disobedience. They prefer protest over peace.
Also, Anonymous isn't a club, or organisation; they aren't a single team, it's the collective actions of thousands of people all over the world who remain, well, anonymous; it's more like a nationality than a group.
I'm not sure what operations group this is, but it's kind of hard to take them seriously when they misspell "anonymous" at the beginning.
