Anonymous is a group of people who have been organizing protests against the church of scientology. They cover their faces, in order to protect and camouflage their identity. Many people at the demonstration had complained that they were followed and harassed by followers of the Church of Scientology, after becoming involved in protesting the church. I also talked to ex-members of the church who came to demonstrate, they said that they received death threats and had been followed as well.
Anonymous, a global movement, has demonstrations every month in front of Scientology Churches all over the world. Anonymous S.F. also has demonstrations every Saturday at the Powel Bart station, across from the Scientology Church performing their “stress tests”.
