Why release of school shooting emergency calls was sought
Authorities have released emergency tapes of callers pleading for police help amid gunfire as last year's school shooting unfolded in Connecticut: http://www.bbc.co.uk/news/world-us-canada-25219654
The recordings contain nearly half an hour of 911 calls made from inside Sandy Hook Elementary School, Newtown, where Adam Lanza killed 20 children and six adults.
The release of the tapes was sought by the Associated Press; its executive editor, Kathleen Carroll, told BBC World Service's Newshour why.
