Obama hs spoken on the dissident murders.
"And the real question was this", he said. "When tested, how would the people of Northern Ireland respond?" (to the murders)

"Now we know the answer: They responded heroically. They and their leaders on both sides have condemned this violence and refrained from the old partisan impulses.

"They've shown they judge progress by what you build and not what you tear down. And they know that the future is too important to cede to those who are mired in the past."
