Obama says guns contribute to police tensions
DALLAS - President Barack Obama says the proliferation of guns is part of the broader tensions that sometimes arise between police departments and the communities they serve.
Obama is defending his calls for stricter gun measures in the wake of the Dallas shootings that killed five and injured seven police officers.
He says police officers at times have very little margin for error in making decisions because guns are so plentiful.
Obama also says the United States is unique among advanced countries in the scale of violence that it experiences, not just through mass shootings but the spate of people shot in his hometown of Chicago.
He says the U.S. cannot identify every trouble individual before they do harm to innocent people, but it can make it harder for them to do so.
