Talk of Colin Kaepernick's decision to sit down during the national anthem reached far beyond football Monday.
And many weren't thrilled with the San Francisco 49ers quarterback's strong words about why he is doing it: To instigate change and challenge authority when it comes to race relations and what he considers police brutality.
Martin Halloran, the San Francisco Police Officers Association president, sent a letter Monday to NFL commissioner Roger Goodell and 49ers CEO Jed York denouncing Kaepernick's "ill-advised" statements and a "naivete" and "total lack of sensitivity" toward police, along with an "incredible lack of knowledge" about officer-involved shootings.
