USPS Mail Carriers Are Getting a "Panic Button"

In broad daylight in Washington, D.C., last year, two armed men attacked a U.S. [Postal Service] letter carrier. He was beaten, bound and robbed.

It was one of more than 400 assaults on postal workers nationwide in 2014, up nine percent in the past five years. That same year, dogs attacked carriers more than 5,700 times.

The Postal Service is shipping all 230,000 carriers new mobile devices with a soon-to-be-activated "panic button." GPS transmits their location to their supervisors every minute.
