Attorney General Eric Holder says law enforcement and other leaders should use the national debate over the use of force to improve relations with the communities they serve.

Holder met Thursday with politicians, law enforcement officials and community leaders in Oakland, California, a city that has seen tumultuous demonstrations against police.

It was the sixth and final city where Holder has convened such a meeting since President Obama asked him to organize such discussions.

Holder said the debate about police relations is an opportunity that shouldn't be squandered.

The meeting was closed to the public, and media were asked to leave after Holder's opening remarks.

Holder has held similar meetings in Atlanta, Philadelphia, Chicago, Cleveland, Ohio and Memphis, Tennessee.
