Relatives of New Yorkers killed by police officers took a knee Tuesday outside City Hall, claiming the so-called "take a knee" movement in the NFL has lost its focus and demanding that elected officials stand up for them.

Former San Francisco 49ers quarterback Colin Kaepernick set the tone for a discussion on police brutality when he started kneeling during the national anthem before games. It's become such a topic of hot debate that even President Donald Trump has weighed in on the matter.

However, families of those killed in incidents of alleged police brutality say some are not taking the movement seriously.

Those who knelt outside City Hall called out the names of each of their loved ones, as well as others killed by police. They commend Kaepernick for starting the discussion on violence against people of color. They say officials like Mayor Bill de Blasio and several City Council members support the movement but have not done anything to stop police violence, including allowing many of the officers involved to still collect a paycheck from the city.

The group specifically wants City Council to pass the Right to Know Act, which would require police officers to identify themselves and inform people when they have the right to not consent to a search.
