Kaepernick says he has been wearing socks depicting police officers as pigs in protest of "rogue cops" who put the community and other officers at risk. Kaepernick issued a statement on Twitter on Thursday, Sept. 1, 2016, after photos of him wearing the socks that show a pig dressed in a police hat began circulating on social media.
