"According to Payne’s office, 'Since September 11, 2001, the federal government has spent more than $13 billion on efforts to achieve interoperable communications. Further, according to a November 2012 Inspector General Report, DHS has invested over $430 million into communications capabilities for its 123,000 radio users since 2003, but department ‘personnel do not have reliable interoperable communications for daily operations, planned events, and emergencies.’ In a May 7, 2012 hearing before the committee, DHS Inspector General John Roth confirmed the failure by testifying that 479 DHS field radio users were asked to get on and use a specified channel to communicate, however, only 1 of those 479 radio users could get on the common channel.'"
