Former Kings forward Matt Barnes' march in response to the death of Stephon Clark will be Saturday at noon at Cesar Chavez Plaza.
A flyer for the event says the march is a call to "Unite. Organize. Act" in response to Clark's death.
Barnes offered to help cover the funeral expenses for Clark, 22, an unarmed African American man who was shot by Sacramento police late on March 18. Officers were responding to reports of a man breaking car windows. They shot at Clark 20 times in his grandmother's backyard.
Clark was holding a cellphone when he was shot; police apparently thought he had a gun.
