“President Obama said the fatal shootings of three Louisiana police were ‘the work of cowards who speak for no one,’ telling reporters late Sunday afternoon, ‘Nothing justifies violence against law enforcement.’
“Speaking from the White House, Obama noted that he had been in Dallas just five days earlier, speaking after a gunman killed five police officers during a Black Lives Matter rally.
“’I said that that killer would not be the last person who tries to make us turn on each other,’ Obama said. ‘Nor will today’s killer. It remains up to us to make sure that they fail.'”
