This is, of course, setting aside the much broader data collection conducted by the NSA. PCWorld writes:
Verizon Communications received more than 320,000 requests for customer information from U.S. federal, state and local law enforcement agencies in 2013, more than 100 times the number of requests from any other country, the telecom carrier said in its first surveillance transparency report.
Verizon received more than 164,000 subpoenas from U.S. law enforcement agencies and nearly 71,000 court orders, including more than 6,300 pen-register or trap-and-trace orders and nearly 1,500 wiretap orders last year, Verizon said.
Verizon is one of a handful of tech and telecom companies that have begun to publish surveillance transparency reports after revelations last year of U.S. National Security Agency programs by former contractor Edward Snowden.
