Colin Kaepernick is doing little to help his own cause

Protestors Rally March Through Downtown Minneapolis

Protestors Rally March Through Downtown Minneapolis

Kaepernick, who famously protested police brutality by refusing to stand during the national anthem last season, tweeted an image over the weekend of a police badge beside a fugitive slave patrol. The images included a caption that read, "You can't ignore your history ..."

In the Facebook video, Castile said he wasn't reaching for his gun, which he had a permit to carry.

This isn't the first time that the freelance quarterback has protested the killing of Castile by Minnesota police officer Jeronimo Yanez during a stop in July of 2016.

The defense pointed towards Castile's drug use, saying it prevented him from listening to officer commands.

Castille's girlfriend, Diamond Reynolds, recorded the scene after the shooting and broadcast it on Facebook.

Kaepernick captioned his tweet: 'The quarterback captioned the image: 'A system that perpetually condones the killing of people, without effect, doesn't need to be revised, it needs to be dismantled!'

"The system in this country continues to fail black people and will continue to fail us", Valerie Castile, the victim's mother, said after hearing the verdict.

"As I'm standing here in this parking lot holding this sign that says Minnesota shame".

Sunday marked the third day of demonstrations against the verdict.
