SAN FRANCISCO (KGO) -- A group that demands justice for Mario Woods, a San Francisco man killed by police last year, is defending Colin Kaepernick and his national anthem protest.
A rally got underway in front of the San Francisco Police Officer's Association late Wednesday morning, near 6th and Bryant.
The association sent a letter to the 49ers and the NFL, saying the quarterback has a lack of knowledge about shootings involving police.
