The union representing Santa Clara police threatened on Friday to boycott San Francisco 49ers games because of Colin Kaepernick's protest against police brutality, KNTV-TV reported.
"The board of directors of the Santa Clara Police Officer's Association has a duty to protect its members and work to make all of their workings environments free of harassing behavior," the group said in a letter to the team, which plays its home games in that city.
If the team does not take action against the quarterback, the letter stated, "It could result in police officers choosing not to work at your facilities."
Earlier this week, the San Francisco Police Officers Association demanded apologies from both the team and the National Football League over what they called Kaepernick's "total lack of sensitivity" regarding their job performance, and also challenged the quarterback to train with their police academy for a day, an offer Kaepernick said on Thursday he was considering.
However, Kaepernick also took note of the findings regarding San Francisco officers' tendency to send one another racist text messages. A panel of three judges also determined that the department showed "institutionalized bias" against communities of color.
"The SFPD has had a lot of issues," Kaepernick said on Thursday, adding that the officers in question were "not only talking about the community, but talking about colleagues that work in the same department."
