Obama also referenced the circumstances surrounding the death of Philando Castile, who reportedly told officer Jeronimo Yanez he was licensed to carry a concealed firearm when he was pulled over on Wednesday in Falcon Heights, Minnesota.
'He let the officer know that he had a firearm and he was reaching for his wallet and the officer just shot him in his arm,' Castile's girlfriend Diamond Reynolds said during a Facebook live stream of the shooting's aftermath.
On Saturday, Obama said: 'In Minneapolis, there was a gun in the car, that apparently was licensed, but it caused, in some fashion, those tragic events.'
But the president also maintained a hopeful message as he looked at the long-term drop in crime rates in the US.
'Violent crime in the United States is the lowest its been since probably the early 1960s. There's an incredible drop.
'That doesn't lessen people's understandable fears if they see a video clip of someone getting killed, but it is important to keep in perspective.'
Obama is scheduled to fly to Madrid, where he will stay for a day before returning to Washington on Sunday ahead of a trip to Dallas next week.
'The president will continue the work to bring people together to support our police officers and communities, and find common ground by discussing policy ideas for addressing the persistent racial disparities in our criminal justice system,' according to a statement issued by the White House press secretary.
