Barrett Brown, who sometimes publicly spoke for the Anonymous collective, pleaded innocent on Wednesday in Dallas federal court to new charges that he concealed evidence, apparently related to a raid on his apartment earlier this year, according to a report. Late last year, Brown also was indicted on charges of threatening an FBI agent in a YouTube video and, separately, for his alleged connection to the breach of intelligence firm Stratfor. In that case, prosecutors did not accuse him of stealing any data, only sharing a link to a dump of credit card numbers. Brown faces up to 100 years in prison for all of the charges. He also has been determined mentally competent to stand trial.
