Hacker Barrett Brown was sentenced Thursday to 63 month in federal prison, with 31 months of that already served, for his guilty plea back in April to being an accessory after the fact in the unauthorized access of a protected computer.

Brown, 33, who has been linked to the hacker group Anonymous, was arrested in 2012 and had been behind bars for more than two years before the plea, according to the Dallas Morning News. Brown also admitted to interfering with a search warrant and threatening FBI agents investigating him.

Courthouse News Service reported that Brown was also indicted for stolen credit card information obtained by Anonymous' 2011 hacking of Austin-based security firm Stratford Global Intelligence, along with an obstruction of justice charge related to the FBI raid on his mother's home.

Brown agreed to plead guilty to one charge from each indictment against him, concluding his criminal case, noted the Courthouse News Service.

In a statement to the court before his sentencing, according to Brown's website, he said that he regretted threatening FBI in videos.

"I don't think anyone doubts that I regret quite a bit about my life including some of the things that brought me here today," Brown said. "The videos were idiotic, and although I made them in a manic state brought on by sudden withdrawal from Paxil and Suboxone, and while distraught over the threats to prosecute my mother, that's still me in those YouTube clips talking nonsense about how the FBI would never take me alive."

Brown charged that by not allowi him First Amendment protections as a journalist puts all journalists and the amendment at risk.

"Every journalist in the United States is put at risk by the novel, and sometimes even radical, claims that the government has introduced in the course of the sentencing process," Brown said in his court statement, according to his website. "I've been employed as a journalist for much of my adult life, I've written for dozens of magazines and newspapers, and I'm the author of two published and critically-acclaimed books of expository non-fiction."
