by hand or by using incineration or shredders. When these activities became known, a protest began in front of the Stasi headquarters. The evening of 15 January 1990 saw a large crowd form outside the gates calling for a stop to the destruction of sensitive files. The building contained vast records of personal files, many of which would form important evidence in convicting those who had committed crimes for the Stasi. The protesters continued to grow in number until they were able to overcome the police and gain entry into the complex.
