When Edward Snowden revealed the government’s vast surveillance programs in 2013, the Obama administration responded with a defense that sounded compelling: the high-tech spying apparatus had stopped terrorist attacks.

I consulted with intelligence and law enforcement sources involved in the case, and they were mystified, too.

The mystery soon deepened when ProPublica gained access to a trove of Snowden’s classified materials.
