WASHINGTON -- In a rare public accounting of its mass surveillance
program, the United States Postal Service
reported that it approved nearly 50,000 requests last year from law
enforcement agencies and its own internal inspection unit to secretly
monitor the mail of Americans for use in criminal and national security
investigations.

The number of requests, contained in a little-noticed 2014 audit
<https://www.uspsoig.gov/story/audit-report/protecting-mail-covers-law-enforcement-investigations>
of the surveillance program by the Postal Service's inspector general,
shows that the surveillance program is more extensive than previously
disclosed and that oversight protecting Americans from potential abuses
is lax.

The audit, along with interviews and documents obtained by The New York
Times under the Freedom of Information Act, offers one of the first
detailed looks at the scope of the program, which has played an
important role in the nation's vast surveillance effort since the
terrorist attacks of Sept. 11, 2001.

The audit found that in many cases the Postal Service approved requests
to monitor an individual's mail without adequately describing the reason
or having proper written authorization.
