NSA activities shouldn’t be aired in public

John Yoo writes for USA Today, June 12, 2013

By combining telephone call records (but not the content of calls) and foreigners’ e-mails abroad — neither of which is protected by the Fourth Amendment — the NSA can at least create the data necessary to quickly identify and frustrate terrorist plans. Of course, the NSA should not receive a blank check. But it is unnecessary, and even harmful, to air its activities in public.
