Clinton: US must face 'hard truths' after Charleston shooting

America has to face “hard truths” about guns and race in the wake of the shooting at a historic black church in South Carolina that left nine dead, US presidential hopeful Hillary Clinton has said.

“How many innocent people in our country, from little children to church members to movie theatre attendees, how many people do we need to see cut down before we act?” the Democrat said during a speech in Las Vegas, referring to mass shootings at a Connecticut primary school and a Colorado cinema.
