First they blamed encryption. Then they wanted websites taken down. Now, they're proposing additional legislation.

Just days after the shocking attacks in Paris, there's a new push in Washington to crack down on encryption and other security tools in an effort to prevent future attacks. Members of Congress have proposed mandatory backdoor provisions, website shutdowns, and expanded surveillance powers. But none of the suggestions have any clear connection to methods used in the attacks, which is resulting in a strange hodgepodge of ideas. Many in the government aren't sure which technologies to blame.

The loudest voice so far comes from CIA director John Brennan, who blames encryption for intelligence failures leading up to the attacks.
