Obama In Dallas For Police Shooting Memorial Service

Obama In Dallas For Police Shooting Memorial ServicePresident Barack Obama visits Dallas on Tuesday to address a memorial service for five police officers killed at a protest against police violence, as he seeks to mend divisions inflamed by the deadliest day for U.S. law enforcement in almost 15 years.

Former U.S. Army Reserve soldier Micah Johnson, 25, gunned down the officers in an ambush on Thursday after expressing anger over recent police killings of black people. Johnson then was killed by an explosive-laden robot sent in by police.

Johnson, who was black, opened fire during a march protesting the police shootings last week of two black men in Baton Rouge, Louisiana and outside St. Paul, Minnesota, the latest in a string of high-profile killings that have stirred a deepest debate on race and justice in America.

Johnson had said he wanted to “kill white people,” particularly police, according to a police account of their unsuccessful negotiations with him.
