There has been no shortage of sorrow-filled words from Barack Obama following each of the tragic mass killings that have afflicted his presidency.
Obama described the wounding of congresswoman Gabrielle Giffords and deaths of six other people, including a young girl, in Tucson, Arizona, last year as a "tragedy for our entire country" and called for a "national dialogue" on how Americans treat each other.
He struck much the same theme in July following the killing of 12 people at a Colorado cinema. A month later, Obama called for "soul searching" on how to reduce violence after a white supremacist murdered six people at a Sikh temple in Wisconsin.
The searing awfulness of Newtown on Friday saw the president in tears, declaring: "We've endured too many of these tragedies in the past few years.
"We're going to have to come together and take meaningful action to prevent more tragedies like this, regardless of the politics," he said.
