From Obama’s press conference last Friday:
PRESIDENT OBAMA: If you look at the reports, even the disclosures that Mr. Snowden’s put forward, all the stories that have been written, what you’re not reading about is the government actually abusing these programs and, you know, listening in on people’s phone calls or inappropriately reading people’s emails.
What you’re hearing about is the prospect that these could be abused. Now part of the reason they’re not abused is because they’re — these checks are in place, and those abuses would be against the law and would be against the orders of the FISC [Foreign Intelligence Sureveillance Court].
