Obama will try to make sense of shootings on Dallas trip

President Barack Obama will fly to Dallas on Tuesday, the scene of the massacre of police officers that, on the heels of two caught-on-video police shootings, has emerged as a tipping point in the national debate about race and justice. Obama is due to deliver remarks at an interfaith memorial service and is expected to meet with victims' families and with local law enforcement officials mourning their own. To some degree, the trip is a familiar ritual for a president who has embarked in recent years on similar consolation missions with relentless frequency. But it's clear that Obama views the moment as distinct. In choosing to the deliver a speech, rather than a private visit with families, Obama has tasked himself with ministering to Americans as they make sense of a frustrating cloud of issues swirling around the shootings.
