The Californian, who is the top Democrat on the Senate Intelligence Committee, said on Thursday that the arrest of two New York women for allegedly trying to build a bomb is a reminder of the threat facing America from within.

“I am particularly struck that the alleged bombers made use of online bombmaking guides like the Anarchist Cookbook and Inspire Magazine,” she said in a statement shortly after the arrests were announced. 

“These documents are not, in my view, protected by the First Amendment and should be removed from the Internet.”
The claim is sure to run into heated opposition from civil liberties advocates who would wholeheartedly reject the claim that the documents are not covered under the First Amendment, which protects the right to free speech. While the right to free speech is not considered absolute, judges have traditionally held a high bar for censoring material based on its status as potentially threatening or offensive.
