SAN FRANCISCO, CA - AUGUST 31: A protestor holds a sign during a demonstration in support of San Francisco 49ers quarterback Colin Kaepernick outside of the San Francisco Police Officers Association offices on August 31, 2016 in San Francisco, California. Kaepernick has come under fire for refusing to stand during the Star Spangled Banner in protest of what he complains is oppression of blacks and other peoples of color. The San Francisco Police Officers Association has written a letter to the NFL and San Francisco 49ers asking for an apology from Kaepernick for comments he made about police officer training.
