Police Commissioner Lee Brown, saying the videotaped beating of a motorist by Los Angeles police focused attention on excessive force, wants U.S. police chiefs to resolve the problem.

Brown was to host a "chief's summit" Tuesday at One Police Plaza on the problem of police brutality and said he had invited the heads of about a dozen police departments to attend.Not attending, however, is embattled Los Angeles Police Chief Daryl Gates, who has been under heavy criticism since the beating.

"The specter of the incidents of police brutality in California and elsewhere has cast a shadow over police departments across the country and threatens to undermine police credibility," Brown said Monday.

"Police brutality in any form cannot be condoned," he said.
