UK's Cameron expresses shock at US lawmaker's shooting

LONDON — British Prime Minister David Cameron has expressed shock at the shooting of a US Congresswoman in an attack which has left Americans questioning the the consequences of the country's sometimes intensely partisan politics.
Cameron said his thoughts and prayers were with Gabrielle Giffords as she fought for her life Sunday, and added that he shared President Barack Obama's belief that "we must never allow violence and hate to extinguish the open political discourse which is our surest protection."
